which could have translated into trouble for Timofeev-Resovskij. On the evening of 15–16 March 1933, members of the Sturmabteilung (Storm Troopers) raided Vogt's villa on the grounds of the KWIH. The action had been taken in response to a denunciation by M. H. Fischer, a physiologist at the Institute, who was seeking to rise in the Nationalsozialistische Deutsche Arbeiterpartei (NSDAP, National Socialist Workers Party). The accusations against Vogt included making payments to the Communist Party, maintaining connections to Russia, tolerating Communist staff members, and dismissing National Socialist staff members. In 1935, Timofeev-Resovskij published the major work, Über die Natur der Genmutation und der Genstruktur, with Karl Zimmer, and Max Delbrück; it was considered to be a major advance in understanding the nature of gene mutation and gene structure. The work was a keystone in the formation of molecular genetics. It was also an inspirational starting point for Erwin Schrödinger's thinking, a course of lectures in 1943, and the eventual writing of the book What Is Life? The Physical Aspect of the Living Cell. In 1937, Timofeev-Resovskij and Tsarapkin were ordered back to Russia by the Soviet government. Going back to Russia was deemed impossible, as they would have to abandon their equipment and work in progress, as well as their students. Also, once back in Russia and under the political distortions of science and agriculture due to Lysenkoism, they would, at best, have to disparage the work they had accomplished in the preceding 15 years. At the worst, they could be subject to the same fate as many geneticists under Lysenkoism who had been arrested, sent to the Gulag and eventually died or were executed. In 1929, for example, Timofeev-Resovskij's former teacher Sergei Chetverikov had been arrested and exiled. During the period 1936 to 1940, many prominent geneticists, including Vavilov, Georgi Dmitrievich Karpechenko, and Solomon G. Levit, were arrested. Many who were arrested later died in the GULAG or were executed. Timofeev-Resovskij’s younger brothers were arrested; the one in Leningrad was executed, but the one in Irkutsk survived. Many of Elena’s relatives were also arrested and perished. Others, such as Nikolai Koltsov and Boris Astaurov, were dismissed from their positions. In this light, they decided not to return to the USSR. Also in 1937, while Oskar Vogt had been director of the KWIH since 1919, he was dismissed from his position by the Nazis; he then became director of the
