Yale doctorate for US geneticist Barbara McClintock (right, 1902-1992). She is in academic robes and taking part in a procession while being awarded an honorary doctorate in 1982 from Yale University. McClintock worked at the Carnegie Institution at Cold Spring Harbor, New York, USA. She is most famous for her work in the 1940s and 1950s on the genetics of maize. She discovered the moving of genes in chromosomes, by observing patterns of kernel colouration. She named these genes transposable elements. In 1983 she received the Nobel Prize in Physiology or Medicine for her work on mobile genetic elements. Yale University awarded 12 honorary doctorates that year. Photographed on 24 May 1982, at Yale University, New Haven, Connecticut, USA.
