Eugene Rabinowitch (1901–1973) was a Russian-born American biophysicist who is known for his work in photosynthesis and nuclear energy. He was a co-author of the Franck Report and a co-founder in 1945 of the Bulletin of the Atomic Scientists, a global security and public policy magazine, which he edited until his death. Early life Rabinowitch was born Evgenii Isaakovich Rabinovich in Saint Petersburg; his parents were a lawyer and pianist. During WWI Rabinowitch studied chemistry in St. Petersburg. Initially a supporter of the Russian Revolution, he and his family fled to Kiev and then Warsaw with the onset of the Red Terror in late 1918. Ultimately fleeing to Germany, Rabinowitch was able to take a course Einstein taught on relativity, and attend academic events that included Max Planck and Max von Laue. He later worked with James Franck at Göttingen. After the Nazis came to power in Germany in 1933, Rabinowitch worked for a year with Nils Bohr in Denmark, before finding a job in London. In 1932 Rabinowitch married Russian actress Anya Rabinowitch, and in 1934 the couple had twins, Victor and Alexander Rabinowitch. Botany Rabinowitch was studying the photochemical properties of chlorophyll at University College London in 1937 and 1938. In the summer he went to Marine Biological Laboratory and began to compile a bibliography on photosynthesis. This work grew into a book published April 1945 that he wrote largely during the summers at Woods Hole. When Rabinowitch arrived in New York City, he was assisted by Selig Hecht, a man whose spontaneous sympathy, friendship and assistance were so generously given to me when I first came to America and felt lost in the human sea of New York. The American Association for Advancement of Science sponsored symposia that Rabinowitch attended: 1939 in Columbus and 1941 at Gibson Island supporting research on the book. Rabinowitch credits Selig Hecht with help in the early stages, and Hans Gaffron for reading the manuscript. After World War II, Rabinowitch taught and researched botany as a professor at the University of Illinois at Urbana-Champaign, continuing his photosynthesis work and publishing the three-volume Photosynthesis and Related Processes. In 1965 he and his student Govindjee contributed an article to Scientific American on the role of chlorophyll in photosynthesis. On the occasion of the bicentential of the discovery of photosynthesis, Rabinowitch penned a summary of the stages of this development. A key step was Joseph
