Abgar Leonovich (15.05.193920.12.2022), grandson of Leon Abgarovich, public figure and scientist, estimates that he saved at least a hundred people. Among those saved was the future Nobel Prize winner for physiology or medicine, Konrad Lorenz. Thanks to Leon Abragovichs intercession, E.M. Kreps trial for counterrevolutionary activities ended with 5 years in a labour camp, and not the highest punishment for the scientist. Thanks to him, Kreps was able to return to his scientific activities. Such activity could not remain unpunished and after the Pavlov session Orbeli was dismissed from all posts, but in 1956 he became Director of the I.M. Sechenov Institute of Evolutionary Physiology. I.M. Sechenov Institute of Evolutionary Physiology, which he headed until his death in 1958. L.A. Orbeli was one of the first native humanist, for whom humanist activity was not less important than scientific. The article is based on report of senior researcher of FGBNU IEM E.T.
