Who is the biophysicist born in 1906 who published major work with Karl Zimmer and N.V. Timofeev-Resovskij?
Karl Zimmer Karl Günter Zimmer (12 July 1911 – 29 February 1988) was a German physicist and radiation biologist, known for his work on the effects of ionizing radiation on DNA. In 1935, he published the major work, "Über die Natur der Genmutation und der Genstruktur", with N. V. Timofeev-Resovskij, and Max Delbrück; it was considered to be a major advance in understanding the nature of gene mutation and gene structure. In 1945, he was sent to the Soviet Union to work on their atomic bomb project. In 1955, he left Russia and eventually went to West Germany.
David Nachmansohn David Nachmansohn (17 March 1899 – 2 November 1983) was a German-Jewish biochemist responsible for elucidating the role of phosphocreatine in energy production in the muscles, and the role of the neurotransmitter acetylcholine in nerve stimulation. He is also recognised for his basic research into the biochemistry and mechanism underlying bioelectric phenomena.
