Kneeling (left to right): crop geneticist Hsien-Wen Li (1902-1976), US geneticist George Beadle (1903-1989), and unknown. Beadle was working as a teaching assistant at Cornell. His later work in genetics led to him being awarded half the 1958 Nobel Prize in Physiology or Medicine. Photographed at Cornell University, Ithaca, New York State, USA.
