Zvi Preygerzon
Zvi Hirsch Preygerzon was a Hebrew writer who spent his whole life in the Soviet Union. Born in Shepetovka, Ukraine, to a Zionist maskilic father and Hasidic mother, he became a committed communist and studied engineering in Moscow. In the 1920s, under the pseudonym A. Tsfoni, he surreptitiously sent his Hebrew writings to Palestine, where they were published in Davar and Gilyonot. Preygerzon was arrested in 1949 and imprisoned until 1955. In the 1950s and 1960s members of the Israeli consulate smuggled his writings to Israel. He worked as a chemical engineer in the Moscow Mineral Institute.
