buds and blossoms

It is getting harder to retain any sense of optimism, but here I'll round up some very tiny personal pleasures and successes from the year that was, just to remind myself that good things still happen sometimes.

In January and February, as my shoulder injury was still limiting the cello playing, I had lots of fun with my tenor sax. (In the course of the year, my shoulder got better, the sax got worse, and the saxophone shop down the road from us closed down, so I very much reverted to string-playing mode.)

In March I signed the contract for a new science book, watch this space!

In May, fleeing the jubilee hysteria, I spent a week in France, first time after 8 years I think, see my flickr album. First thing I missed in the streets was newspaper stalls. And people smoking. Both being replaced by people glued to their phones.

In June, I launched an effort to lose the fear of flats, mainly by learning bits of the fourth cello suite which is in Eb major (3b).

In July, I used up a random bag of seeds flying around and grew six dwarf sunflowers which lit up my windowsill for a long time, see photo below (and more on flickr). And learned some botany - after the first flowers faded, I noticed other buds forming, so cut the faded flowers and got smaller secondary flowers as well. Which kept them going into September.

In August I used the famous 9-Euro ticket to visit 9 cities in 9 days. I also had a ticket in June, when I passed through Germany on the return from France, but then I didn't have much time to use it thoroughly.

Back at Oxford, I had the privilege to meet Caroline the Musical Saw Lady at Elder Stubbs Festival and try her Stradivarius saw. Soon after I found a 26" saw on ebay which works very nicely both for playing and for actual woodwork.

Later in August, I was very surprised to discover an origins story for my Wolff ancestry.

On Sept first, I launched the second season of my blog series Every picture tells a story where I share one (or several) family photo every week.

In late September, I made a surprise discovery that very nearly knocked me off my feet: 160 poems written by my great-grandfather Heinrich the cellist after meeting and falling in love with my great-grandmother. Like more famous writers before him, the budding poet used lots of botanical metaphors, too.

In November, I managed to fix my aunt's old violin which had spent more than half a century in different attics. Turns out I really enjoy playing it too, I wasn't expecting that. Having started the year playing mainly alto recorder and tenor sax, I'm now closing it playing mainly violin and cello. Also, it's handy to be able to switch instruments in response to which strains this old body is still willing to tolerate.

Also in November, when the situation at the bird site got out of hand, I came prepared, as I had already set up a mastodon account back in 2018 (when tumblr banned the infamous female-presenting nipples). I also rejoined tumblr, but that isn't working nearly as well as Mastodon these days.

In December, we had a lovely cold snap and I managed to fit two afternoons of wild skating at Port Meadow.

Professionally, I have managed to publish my complete set of 24 features in Current Biology this year, one in every issue, which is always a very satisfying thought.

Oh, and thanks to a generous Santa, my Lost Cities series is now also taking the shape of a collection of matching books full of old postcards. Will do a separate blog post about these in the new year.

Executive summary: ship still sinking, band still playing.

desperately searching Wilhelm

Every picture tells a story, season 2, picture 17.

When the three children from the bakery in Dörndorf (Silesia) grew up, Hedwig the milk maid didn't think much of her sister Emma, who allegedly had the habit of sneering at Hedwig's "smelly" employments in agriculture. She was very fond of her brother Wilhelm though. He went missing in the last months of the war and Hedwig, then transplanted to west Germany kept looking for him for many years. He never did turn up, and we still don't know what happened to him.

So what we know:

Wilhelm Karl (Willi) Geppert
born 12.11.1916
1934 finishes apprenticeship with master butcher Paul Loge at Heinersdorf: Gesellen-Brief 27.9.1934
Wanderschaft documented until 15.4.1938, mostly working in the region of Kreis Frankenstein, Silesia.
2.3.1945 last post from the front, near Königsberg, East Prussia. Address: FP Amt Heiligenbeil, Braunsberg, Ostpreussen.

As she missed him so much, Hedwig kept lots of photos of him, and he tends to look cute and friendly in these. Here's a selection with a few open questions:

first communion

Wilhelm on the right, no idea who the others are. Maybe he lodged with them during his apprenticeship?

We don't know who his girlfriend was either.

and finally, if anybody recognises this Pension Roseneck, I have no idea where this might be. None of the eponymous guest houses I can find online has anything like the characteristic architectural details around the windows seen here. Photo dates from 1942. Update: It is marked on the back with greetings from Badenweiler, which may be a clue. Badenweiler is a spa town in the Black Forest, but I still can't find Pension Roseneck there.

Should anybody have any answers to some of the many questions I am raising in this series, please leave a comment here (I'll need to vet it, so it may take a few days before it goes public) or contact me at michaelgrr [at] yahoo [dot] co [dot] uk

nanoworld's submarines

Back in the 1990s, when I did research on the molecular machines in the cell and got excited about artificial nanomachines inspired by these, I wrote a whole book about this nature vs technology on the nanoscale thing: Travels to the Nanoworld.

In recent years, I haven't covered this field all that much, as I've move more into ecology/environment direction, but C&I kindly asked me to do a feature on miniature machines pegged to some exciting things that came out of Cornell's labs, so I did. It is out now:

games time

Every picture tells a story, season 2, picture 16.

It's also the season for board games, so here is Frieda the pianist as a budding granny playing a game with her first three grandchildren and their parents. I think I've seen this game before but can't remember what it's called or how it works.

What interests me more about this photo is the surrounding, with Frieda's piano in the background on the left and her middle daughter's violin on the top of it - although that middle daughter had already married and moved to a different country by that time. It boggles my mind that nobody alive has any memories of this instrument, even though it was always there for all to see. Also on the piano a portrait which I think is of Frieda's father, Heinrich the station master of Minden Stadt. Above the piano on the wall that could be a portrait of a composer (Schumann?).

Around the corner on the wall to the right of the piano, two family portraits. I've identified the one on the left here, and the other one is a portrait of her with Peter the customs officer, possibly taken on the occasion of their engagement. We still have both of these, still in their frames, but I don't have them here, will have to do a separate entry with the entire collection of photos seen around Frieda's flat. Heck, I may even be able to re-unite them with these tasteful antler-lamps. Watch this space.

PS come to think of it, I did a re-enactment of the violin lying on the piano, when both crossed paths again in Düsseldorf this June:

Update 25.12.2022 - I found a photo I took of the missing photo, still in the same frame, and positioned on the piano:

fighting invaders

The last feature of the year is about invasive species, one of the key causes of biodiversity loss, which has been the focus of the COP15 summit at Montreal that ends this week.

We, Homo sapiens, are of course the most invasive species of all, and most of the others have invaded in our footsteps. They often travel as stowaways, such as rodents on ships, but in some cases have also been spread intentionally by people wanting to "enrich" their local flora or fauna.

For the feature I have rounded up some examples of such accidental or stupid invasions, along with new ways developed to fight back against harmful invasions.

dancing chemist

Every picture tells a story, season 2, picture 15.

I hear it's party season out there (although I'm more in hibernation mode myself), so let's have some party pics. Richard the young chemist managed to survive WW2 guarding some telegraph station near the arctic circle without getting promoted or noted in any form, which is why after the war he got very swiftly got back into teaching and soon became headteacher of the Göttenbach-Gymnasium in Idar-Oberstein (a Gymnasium is a selective secondary school, a bit like grammar schools in the UK). He started there as acting headteacher in 1950, and was promoted to the proper rank of Oberstudiendirektor in 1952.

There are obviously all kinds of photos of him at work and with the teaching staff, but let's have some party pics which I found floating around randomly, so I have no clue what year they were taken, what the party was about, and who the other people were. All hints welcome.

and another one, I think I found both in the same box of random stuff:

NB his other subjects were maths and physics, I just kept the chemist of the season 1 episode because he's wearing a lab coat in these photos.

a violin gone missing

Some thoughts on

Gone: A girl, a violin, a life unstrung

Min Kym

Viking 2017

I still remember reading the news when Min Kym’s Stradivarius violin was stolen from near her table in a Pret a Manger outside Euston Station in London. (On our way to St. Pancras we usually have coffee at a Pret a couple of hundred metres earlier, but I think on one or two occasions I may have used the same one.) So it felt a bit weird buying a memoir pegged to that story, but then again, it crossed my path when I had just restored a neglected family fiddle, so was on a violin vibe anyway and keen to read the violinist’s account of her relation with her instrument.

As the guardian of several old string instruments that are a bit less valuable than virtually all of those mentioned in the book, I am in two minds about the story of the author and her violin. I can relate to the emotional bond she describes, especially to the instruments that have a long and well-documented history, as the Strads usually have (but some of my more modest instruments also have to a certain extent).

But then the value thing comes in and disturbs the romantic story of emotional connection – Kym doesn’t appear to consider any instruments worth playing if they have fewer than six figures on the price tag. After her beloved Strad was stolen, she duly got the megabuck (literally) payout from the insurance, but by the time the stolen instrument was recovered, the money had dispersed this way and that, as life happened and she was unable to continue her glamorous solo career without the one instrument that meant everything to her. So she wasn’t able to pay back the insurance and thus couldn’t get the instrument back.

Which in a way reflects the typical situation that even celebrated soloists find themselves in these days – the prices of these instruments are so astronomical that no amount of gigging and recording will pay for them. If they’re lucky they can find investors who will buy the instruments and let the musicians play them. This can be a win-win, as appearances with a top player will also boost the value of the instrument and thus the wealth of the investor.

This is tragic in a way, but it was to be expected if you have a very limited resource in a competitive capitalist environment. Arguably, by hyping the importance of playing only the best 17th/18th century instruments and nothing else the stars of classical music have dug this hole for themselves. Had they kept quieter about it, and from time to time agreed to play on instruments built by mere mortals, they might still be able to afford the top of the range.

Obviously, there is a similar race going on for the quality of the performers themselves – in a global competitive environment, where you can easily compare recordings made by everybody in the field, the top edge of the triangle gets higher and sharper, but that doesn’t help the rest of us, who are playing our ordinary instruments as best we can near the bottom of the pile.

Both of these developments are the opposite of what we are trying to do in folk music, encouraging everybody to join the fun, with whatever instrument they can find on a flea market. Personally, I am convinced that I am learning more about music (including the classical repertoire as well as folk) by trying to play it myself than by listening to some superstar having fun with their Strad.

So I’m afraid my empathy doesn’t go up in line with the price tag – if somebody has their much-loved folk fiddle stolen I can appreciate that it means as much to them as the Strad meant to Kym, even if there are five orders of magnitude between the market prices of the instruments. Although I’ll also continue to read stories of Stradivarius instruments (such as the six collected in this book I reviewed earlier) as tales from an alien civilisation.

The edition I found at a charity shop - appears to be a first edition and it is signed, so maybe it could become valuable too - if and when the author's solo career recovers. The blue dust jacket has a violin-shaped hole revealing the black of the hardcover binding underneath, which is kind of clever alluding to the dark hole in the author's life as well as perhaps the process of carving the instruments out of trees?

string theory

Plague Year(s) Bach Project, update plus violin news

Slow progress - have now re-memorised the minuet in D minor to complete movement 2.5, one of the more difficult movements in the first three suites. It still needs sorting out with the metronome. Also, getting the hang of the bourrees in Eb minor, with half of the first (much longer) bourree memorised and the rest of it beginning to make some kind of sense when I play it.

Now looking forward to a few quiet weeks to to advance a bit more.

In other string-playing news, I managed to restore my aunt's violin, which hadn't seen the light of day in more than half a century, to a playable condition, and actually quite enjoy playing it. Waking up an instrument neglected for decades, it would be rude not to play it, right?

Although the fingering on the violin is different from the cello, and the hand is the wrong way round, I found to my surprise that the automatic playing transfers quite quickly. By this I mean that I think of a sound and the fingers will find it - John Holt explained it nicely: when you whistle a tune you don't plan what your tongue and cheeks and lungs are doing either. Playing the violin in the afternoon and the cello in the evening, I have one or two violin related errors when I pick up the cello (ie putting down the 3rd finger where I should use the 4th), so I guess it is important to practice both to make sure the cello code doesn't get overwritten with violin code (that's my string theory at least). But otherwise all good.

So far, I'm only playing folk tunes that I know by heart (eg those from the Oxford Slow Session), and they do tend to come out ok once I figured out which note to start on. Here is a video recorded one month into the fiddle-playing experience - I picked a slow tune, Inisheer, to demonstrate the sound of the instrument, which I think is actually improving as it wakes up from its long slumber, and as we are learning each other's ways. Playing these folk tunes also made me realise to what extent they are written to fit into first position on the fiddle - I've effortlessly played a few that I still find awkward on the flute. Oh, and we made our debut appearance at the Slow Session last Sunday.

Heinrich the cello and Christa the violin. Come to think of it, their human namesakes and previous owners may or may not have met in Idar Oberstein in the 1950s. It may be too late to find out if they did. The attic years of both instruments likely started within 6 months of each other, the cello's after Heinrich's widow died in October 1961, and the violin's after Frieda the pianist died in April 1962 (until then the violin had resided on the top of her piano). Oh, and Frieda's piano also went into storage at that point, but it was the first of the three instruments to see daylight again, at the end of 1968.

family portrait

Every picture tells a story, season 2, picture 14.

Writing the entries about the family of baker Adam Eberle in Lorsch in the first series, I thought that I didn't have a photo with all four children. Well I was mistaken, I do have at least a photo of a family portrait (not sure where the original is):

The boy is Peter, the youngest child. He was born in 1900, and his sisters in 1893 (Anna), 1895 (Babette) and 1897 (Dina). My guess would be that the photo may date from 1909/10.

Their mother is Anna Barbara Schütz, born 1860 in Nieder-Liebersbach. She was Adam's first cousin, his mother was her father's sister. So they only have three pairs of grandparents between them. All three families (Schütz, Schmidt, Eberle; further back: Treusch, Röder, Quick, Bangert, Kadel etc.) have been settled in the Odenwald region since the late 17th century, at which time inward migration from Switzerland, Thuringia, and elsewhere helped to revive the Odenwald villages depopulated by the 30-Years War (for details, see the update under this entry in the first series).

For easier comparison, I'll throw in the earlier photo with their house, which I shared before:

soundscape evolution

Soundscape ecology is beginning to get more attention these days, but what about soundscape evolution? It is intriguing to think that all the biological sounds we associate with life going on around us only evolved within the last half-billion years. After all, the microbes that dominated our planet for most of its lifetime have no way of producing sound.

The origins of biological sound production, first pinned to the rise of grasshoppers some 250 million years ago, are moving back in time, however, as more and more living species are being recorded as sound producers. A recent study suggests that the common ancestor of all terrestrial tetrapods, that fish that started to walk on land some 400 million years ago, was already vocal.

Inspired by this finding, I had a look at the evolution of our soundscape for my latest feature which is out now:

travelling saleswoman

Every picture tells a story, season 2, picture 13.

After Julius the shopkeeper and later textile businessman had to leave Königsberg he settled in Bad Nauheim and tried to start a new textile business from there based on his address book if not much else. From November 1945 he and Helene (and whatever other family members washed up) lived in a single room in Frankfurter Str. 12, an art nouveau villa which the family later bought, and which you can see here.

Julius died in 1950, aged only 66, which was possibly related to the tropical disease he caught as a young man in Africa. Julius had bullied his younger daughter Esther into studying economics against her wishes. She therefore sported the title of a Diplomkaufmann, which together with her last name of Düsselmann made for a lot of manliness on this woman's business card. Working with Otto Hummel first at Königsberg and then at Reichsuniversität Posen (Poznan), she had even prepared a doctoral thesis about the eastern European trade which became pointless after the war, had worked at Frankfurt with Ludwig Erhard between 1945 and 1950, and then after Julius' death felt obliged to keep his business alive. This involved her driving around as her own travelling saleswoman, for which purpose she got a car, namely a Fiat produced in Germany by NSU, so it was known as an NSU-Fiat. At this point, nobody else in the family had a car (people were still civilised and lived in cities and didn't need one!), so it made a big impression on her teenage nephew, and there are a few photos of her with the NSU-Fiat:

I love this one which kind of reflects her imposing nature.

I have no idea who her fellow travellers may have been.

Could be her sister Ruth in the passenger seat not sure.

The closest match for the car I could find online is this:

I gather it could be a Fiat topolino 500C Belvedere, but have no strong opinion on this.

Esther's saleswoman life continued until 1960. Then, as compensation payments for the lost factory in Königsberg enabled the family to buy the house, she gave up the textile business and ran a bed and breakfast for spa visitors.

the right instrument

A recent obituary in the Guardian came with a photo of the person playing the flute, so I read it although the name didn’t ring a bell. As it turned out, flautist Atarah Ben-Tovim (with her husband Douglas Boyd) was the author of a book that I read in the 1990s and that has influenced my life more than most books I read: The right instrument for your child.

As I recall it, the book is extremely good at pointing out all the little things that may become a deciding factor in whether or not a young (or even not so young) person is attracted to a specific instrument and will also stick with it. Such as the physical energy you can pump into a cello, which suits a slightly more assertive child, shall we say. Or that flute fingering is easy when you transfer from the recorder.

I believe (with the authors) that more consideration on the instrument choice could save a lot of people from an unhappy learning experience. Too many people just go for piano or violin as the default without considering the personality of their child and what kind of instrument would be a good match.

The book helped me a lot in kicking off the musical education of my children, which then rubbed off to my own, belated learnings, so it helped to generate many person-years of music making in this family alone, just imagine what its effect may be on its entire readership. I think of this book as plan A, with the equally interesting “Never too late” by John Holt, being the plan B. There are two more recent editions than mine, but it seems to have gone out of print after the 2012 release.

Like most of the things I'm obsessing about these days, this is related to my musical memoir project, specifically to chapter 4.

three sisters from East Prussia

Every picture tells a story, season 2, picture 12.

Several of the numerous children of the East Prussian patchwork family moved to West Germany in the 1920s, some possibly later. Of the four children the couple had together (on top of the ten from their previous marriages), the oldest, Karl Faust, died in 1945. His three sisters are shown here in a 1955 meetup in Lippstadt, first without:

and then with the surviving husbands:

At the top that's from left to right Luise (married name Hießke), Auguste (Kosmowsky) and Hanna (Krieger). Auguste's husband Ernst Leopold the steel worker had died in 1945. We don't know much about the Hießke family living in Lippstadt, as contact with them wasn't as close as between the other two families.

Update 26.11.2022 Expanded the title as I just realised I used three sisters before, in season 1.

decline and fall of twitter

So the last time I wrote a blog entry about twitter was on the occasion of my 10th anniversary on the site, in July 2019. Sadly it now looks as though the blue bird is being strangled, plucked and roasted and may not be around for the 14th anniversary of my signing up.

Luckily I already had a mastodon account set up back in 2018 (then as a tumblr alternative), so now I only had the task of transferring my twitter network to the mastodon address, and that has worked surprisingly well. Last Monday I ran one of the relevant programs on my twitter contacts and discovered more than 150 people to follow. Many followed back fairly swiftly - it's so nice to be in a place where people are still curious about each other. Feels a lot like early days twitter, actually, when people were flooding in from the ruins of MySpace.

Since then, my Mastodon timeline is as lively as the one on twitter used to be. While it's numerically fewer than 10% of the contacts on the bird site, I guess that many of the accounts still listed as followers and/or followees over there are no longer active.

One thing still missing for Mastodon is Toot buttons on the websites where I find content to share. For instance on EurekAlert, the easiest way to generate a toot is to use the tweet button and then copy/paste the tweet (before hitting tweet, as twitter may abbreviate the links in ways that don't survive copy/pasting from the published version. I'm also continuing my calendar-year based twitter threads for features published, features transferring to open archives, and books read/reviewed until the end of the year and will relaunch them on Mastodon in the new year. The Every Picture series has already got its Mastodon thread which is now up to date.

So maybe it's time for final stats:
Following 2239
Followers 1572
Tweets 39k - may have to log in to get a precise number? Oooh, yes, after logging in it's 39066 (on 23.11.)

Mastodon looks like a welcoming sort of place:

Mastodon's official welcome pic, which I usually see before I log in.

so do find me there:

@proseandpassion@mastodon.social

I'm planning to stick with my general approach of using the short message sites to funnel attention to longer formats such as blog entries, which again guide the interested reader onwards to seriously long formats such as features and books.

PS to do justice to the title of this entry, I will compile here a few resources on the continuing implosion of the bird site, as I find them.

neanderthals alive and well

Reflecting on the Nobel prize for Svante Pääbo for his revolutionary work on Neanderthal genomics (which I've been covering for nearly 20 years), it struck me that there is now a lot more Neanderthal DNA walking around than there ever was when being a Neanderthal was still a thing. Back of the envelope calculation: if we have 2% Neanderthal genes on average in 5 billion non-African people, that gets you easily to the equivalent of 100 million Neanderthals alive today. Before they became extinct, there never were as many as 100,000 of them alive at the same time, so we're talking a 1,000-fold rise. If you have to become extinct, that's not the worst way to go.

Those Neanderthal genes are still around for reasons, as they were beneficial to our sapiens ancestors, and science is now beginning to understand in which ways our Neanderthal heritage shapes our physiology, which of course has implications for medicine. Which explains why Pääbo got the prize for physiology or medicine even though his patients have been dead for 30k years.

Moreover, Neanderthals are also coming back to life in the sense that paleogenomic studies are now revealing details of family relations, diet etc.

All of which was a welcome excuse to write another feature on Neanderthals (I even have a tag for them), which is out now:

As the bird site seems to be going the way of MySpace, I will start a Mastodon thread in the new year, just couldn't be bothered to redo all the copy-pasting for the 21 features already out this year.

cousin Charlotte

Every picture tells a story, season 2, picture 11.

These stray cousins have a tendency to be called Charlotte, so this one is Charlotte Kosmowsky, born 1919, daughter of the forester Albert K. in East Prussia (we saw her in that photo with the dead stag). Not to be confused with Lotti in Berlin. Here are a couple of portraits during WW2:

During WW2 she was in Kiel, where she married a guy whose name we don't know. Strangely, we do know the date of his death though, 11.12.1974, and they had a son called Frank-Rüdiger. If that rings any bells, do give me a shout. After the war, her family and her dad, forester Albert K, ended up in Hennef, Sieg (15km east of Bonn) where this photo was taken in 1970:
That's Albert on the left, then Charlotte's son and Charlotte. On the right, her cousin Fritz and his wife. UPDATE 2.1.2023: Flickr user Colin Webb has kindly given Charlotte a blush of colour, see her on his facebook page.

bees and astrobiology reviewed

When I talk about book reviews, I have separate tags for books I review and for my books being reviewed, but this may be the first time I have to use them in the same entry, because the November issue of C&I contains both a review of my book Astrobiology (3rd ed.), and my review of the absolutely brilliant book

The mind of a bee
by Lars Chittka
Princeton University Press:

All the buzz about bees

an old family fiddle

The last time I visited my aunt at Tulette (Drome, France), we were talking about the young cellist in my family, and it suddenly occurred to her that she once had a violin, growing up in Aachen in the 1930s, never got on with it, but the instrument was still buried in her attic in Tulette.

When her house was cleared out after she died, my cousin found this violin and was surprised as he hadn’t heard the story of his mother’s failure to learn the instrument back in Aachen. In June I visited my cousin and retrieved said violin with a view to bring it back to life. It looked like this:

i.e. soundpost, bridge, chinrest, and three strings missing, no bow, a bit scratched, but otherwise ok. In the photo it sports an improvised bridge I made from half a bamboo ring. I kind of like the dark look with the light borders and I don’t mind the scratches. So I took it to a luthier for an appraisal and was quoted £250 (plus strings) to get it into shape, with the perspective that it might be worth up to £500 in perfect condition. Not a really good instrument but “good enough for folk” as we like to say in folk circles, semi-ironically.

While I was pondering whether or not to do this, I discovered at Oxfam an old book on The Making of Stringed Instruments for £ 4 (George Buchanan, 1989). As it happens, it contains a very useful page on the part I thought I couldn’t do, namely putting the soundpost inside the instrument. I cut the post from a random bit of wood I had lying around. Turns out with a bit of wire bent to make a holder, a tool I made from a broken spoke, and four or five attempts, I was able to fit it in. One crucial bit of information from the book was that one can easily unplug the peg that holds the tailpiece, and thus get a hole through which one can actually see the placement of the soundpost very nicely.

I bought a bridge online for £ 2.50, and the book was again very helpful on how to shape it correctly. I had a set of violin strings sitting around which I put on (I kept the historic E string though, see how long it lasts!), and now it’s beginning to look like a proper violin:

(in the battered historic case which is lovely but not very practical for sessions, it doesn't offer much protection and doesn't have shoulder straps)

And it may be me having a Pygmalion moment here, but I do like the sound of it. Will practice a little to be able to record a video that’s not too much out of tune. UPDATE: Here's my attempt at playing Bear dance and Hunt the squirrel on day 7 of trying to play the fiddle.

Meanwhile I spotted a Stentor student fiddle at Gumtree sold for £ 25 from an address where I cycle past every week, so I picked that up on my way – it came with two bows, and I’ll probably use the case and the chinrest for the old fiddle. It also had two packs of rosin, one new and one maybe used three times.

Oh, and with hindsight, looking at the old photos taken in my grandmother’s flat at Idar-Oberstein, I recognise the violin case sitting on top of the piano (eg here and here). Better than the attic, and I do wonder whether it was ever used in those years (until 1961).

Along with Heinrich the cello, Frieda the piano, and Blue the guitar, this is the fourth instrument we have that’s been in the family for more than half a century (and I’m not even counting my school recorder, which isn’t a very good one). In this sense, this should have been episode 3 in the much-neglected all instruments series, but it comes in at number 22. Oh, and maybe I should list my house as a shelter for neglected instruments.

Update 2.12.2022 After I figured out where the gears and the brakes are on this thing, I began to realise that the historic E string didn't sound as good as the new strings, so I replaced that one as well. And with the full set of new (Dominant) strings, the instrument is really sounding quite lovely. Oh, and I'm creating a violin tag, as I feel I will obsess about this instrument some more.

guessing the great-grandmothers

Every picture tells a story, season 2, picture 10.

This photo from Silesia is a bit of a guessing game, but I think we have Gellrich family on the left, and Geppert family on the right, with their shared grandchild and two uncertain great-grandmothers? In which case we're looking at the 1940s.

(This is a high res scan in case anybody wants to zoom in and try to ID people.)

Which would mean that, identifying the grown-ups by their birth names as usual, we would have from left to right, Paul Gellrich sen., Hedwig Scholz, then the old lady could be the mother of either, i.e. Mathilde Metzner or Anna Kleße respectively (although I tend to prefer the latter interpretation, as I think she looks a bit more like Hedwig Scholz). The Gellrichs lived at Groß-Olbersdorf, Kreis Frankenstein, and we last saw them at the wedding of their daughter Maria.

On the right we have Martha Stephan and Wilhelm Geppert, the baker based at Dörndorf, Kreis Frankenstein. Of the Geppert family, three great-grandparents hailing from Reichenstein and Kamitz are known to have died earlier, with the only potential survivor being his mother, who was called Ottilie and was born either Scheidthauer or Büttner (conflicting info in different documents relating to her son.) Of the great-grandparents' generation we have no specific dates, places or other photos to compare this to, so very big question marks over these two.

going bananas

Various things have gone completely bananas around here, to the extent that Der Spiegel called the UK the banana island, so a feature about the evolution and ecology of bananas appears to fit the zeitgeist. Starting from a recent genomes study, I also looked at the problems with pests and diseases, as well as the economic structures that gave bananas a bad name. Oh, and Jules Verne is in there too, as he made an important contribution to banana history.

The resulting feature is out today:

tumblr resurrection

Back in February my tumblr account was terminated and I couldn't be bothered to start over again, but with all the things happening at twitter now, I was intrigued to hear on Wednesday that tumblr has - after nearly four years - given up on banning female presenting nipples. I thought that sounded like a step in the right direction, so I launched a new attempt, this time as prose2passion.

I'm also using Mastodon more regularly in an attempt to be better connected there when twitter collapses. It's amazing how much more activity I've seen on Mastodon since Musk carried that sink into twitter HQ. Still haven't tried pinterest.

I even tried to log into my old MySpace account but failed (even though I am quite sure I have the correct login details). Maybe they block logins that haven't been used for ten years.

my new profile pic on tumblr (dates from 2019 though). Am likely to keep the bookish theme there, so this seemed to fit. The book is A diagonal dos tolos by Santiago Lopo.

horses for Hedwig

Every picture tells a story, season 2, picture 9.

When Hedwig had her photo taken with all those milking accessories, a horse crashed the photoshoot. Here she comes again, a bit later in life, with more unexplained horses.

This photo where she seems to be enjoying being the only woman in the presence of a bunch of young men dressed up for riding, hunting, or I don't know what, was taken at the Hammoser farm in Brase, now part of Neustadt am Rübenberge, Lower Saxony, where Hedwig and part of her family arrived after being evicted from Silesia.

By contrast, the location for this one is far from clear, could be Brase as well, but could still be Silesia. The guy driving the carriage is allegedly Hedwig's brother in law Max Fuss, who wouldn't have been in Brase, normally.

We've failed to track a pub of a name beginning with "B. Bein" (as per the large sign behind Hedwig) to Brase too. So, it's all slightly confusing.
