Neurologist Rita Levi-Montalcini turns 100 today, and I understand she's fighting fit and still working. According to a profile published in Nature a few weeks ago, she is the first Nobel laureate ever to live to 100 (which of course is partially due to the fact that there are so few women getting the prizes!)
Her autobiography In praise of imperfection sounds interesting and is available from various Amazon marketplace sellers in the US and the UK. Somebody could have thought of reprinting it on the occasion of this special birthday?!
