|Berezin (25 April 1931 – 14 July 1980) was without a doubt the first person to really work with supermathematics, that is mathematics with commuting and anticommuting variables. His worked paved the way for mathematicians and theoretical physicists.|
Berezin also made many important contributions to quantisation, he is best known for the notion of integration with respect to Grassmann variables and the generalisation of the determinant to a “super-determinant” known as the Berezinian.
Alexander Karabegov, Yuri Neretin and Theodore Voronov  have written a survey of Berezin’s work which has appeared on the arXiv.
Their survey concentrates on Berezin’s contributions to representation theory, the general concept of quantization, and supermathematics.
