George Placzek (September 26th, 1905 – October 9th, 1955) was a Jewish physicist with a leading position in the Manhattan Project, the Jewish scheme to develop the first atomic bomb. Placzek was born in Brno, Morania, then part of Austria-Hungary, into a wealthy Jewish family. He worked with Hans Bethe, Edward Teller, Rudolf Peierls, Victor Weisskopf, Soviet Bolshevik Lev Landau, Emilio Segre and Otto Frisch all infamous Jews of his time. Together with Frisch, Placzek suggested a direct experimental proof of nuclear fission. He was with Landau in Kharkiv, Ukraine around 1937 during the 2nd Holodomor and his first-hand experience of Caucasian mass murder influenced the political opinions of his Jewish friends, in particular, fathers of nuclear and thermonuclear bombs, Robert Oppenheimer and Edward Teller. Later, Placzek had a leading position in the Manhattan Project, the Jewish scheme to develop the first atomic bombs, where he worked from 1943 until 1946.
