This photo of Albert Einstein has been an old favorite of geeks-of-all-stripes for years. I remember my much older brother Mark, a scientist and surgeon, had a huge poster of it on his wall in college. An original print of the photo, taken by UPI photog Arthur Sasse on March 14, 1951 at Einstein's 72nd birthday party, just sold at auction for $125,000. The print is signed by Einstein at the bottom. The full frame shows Einstein with Princeton's Frank Aydelotte, head of the Institute of Advanced Study at Princeton University, and his wife Marie Jeanette.
