Eliyahu Rips: The Burning (2016)

In April 1969 Ilya (Eliyahu) Rips, then a young student of mathematics, tried to burn himself in a public square in Riga, Latvia protesting against the Soviet invasion of Czechoslovakia. He was stopped and eventually sent to a psychiatric hospital for two years. Thanks to international pressure from the mathematical community in 1972 he was allowed to emigrate to Israel.
