Henryk Grossman was a Marxian economist who expanded on Rosa Luxemburg's crisis theory. Despite the loss of some of his comrades to Stalinism in the purges including Boris Hessen and Karl Radek, and his close connection with eminent council communist Paul Mattick, his biographer, Rick Kuhn, had extensively confirmed his conformity to Stalinism. He died shortly in 1950 after gaining  an academic position as a professor of political economy in an East German university.
