Biologie, was published in Germany while they were in the Soviet Union. In 1948, due to Lysenkoism, there were grave consequences for the institute in Sungul' in general and for Zimmer and Timofeev-Resovskij in particular. The book was put on a forbidden list and the laboratory was not allowed to conduct research on its topics. In 1955, Laboratory B was merged into the newly created second nuclear weapons design institute Nauchno-Issledovatel’skij Institut-1011 (NII-1011). During the merger, the radiopathology section of S. A. Voznesenskij's radiochemistry department was transferred to Combine No. 817 (Ozersk), and Timofeev-Resovskij and 16 members of his department were transferred to the Ural Branch of the USSR Academy of Sciences, in Sverdlovsk (now Ekaterinburg). After discharge from the Sharashka, Timofeev-Resovskij visited Moscow, Leningrad, and Kiev. In these locations, he was able to visit physicists Peter Kapitsa, Lev Landau, and Igor’ Tamm, the biologist M. V. Volkenstein, and the mathematician A. A. Lapunov. In Sverdlovsk, Timofeev-Resovskij organized and became the head of the Department of Radiobiology of the Ural Branch of the Academy of Sciences. In 1956, he also founded an experimental station and summer school at the nearby Lake Miassovo. The experimental station conducted radiological research on radiation and population genetics. This summer school contributed to keeping classical genetics alive during the period of Lysenkoism, which officially ended in 1964. The Miassovo summer school became famous among Soviet scholars and students. Among the lecturers were mathematicians Aleksei Lyapunov and Ivan Poletaev, biophysicists Lev Blumenfeldt and Mikhail Volkenstein, biochemist Simon Shnol, geneticist Raisa Berg and Vladimir Efroimson. The school produced numerous geneticists, ecosystem biologists, biophysicists and radiation biologists. In 1964, Timofeev-Resovskij organized and became the head of the Department of Radiobiology and Genetics, at the Institute of Medical Radiology of the USSR Academy of Medical Sciences, in Obninsk, Kaluga District. In the department, Timofeev-Resovskij supervised and headed the Laboratory of Radiation Genetics and the Laboratory of Radiation Ecology. There were two other laboratories in the department, the Laboratory of Cellular Radiobiology, headed by V. I. Korogodin, and the Laboratory of Molecular Radiobiology, headed by Zhores Medvedev. The first group in the USSR to study Arabidopsis thaliana was established by Timofeev-Resovskij during his time in Obninsk. Two well known figures in genetics started their research and received their degrees at Obninsk under Timofeev-Resovskij. One was Nikolai Bochkov, director of the Institute of Medical Genetics, in Moscow; the other was Vladimir
