Vasily Semyonovich Grossman (Russian: Васи́лий Семёнович Гро́ссман; 12 December [O.S. 29 November] 1905 – 14 September 1964) was a Soviet writer and journalist. Born to a Jewish family in Ukraine, then part of the Russian Empire, Grossman trained as a chemical engineer at Moscow State University, earning the nickname Vasya-khimik ("Vasya the Chemist") because of his diligence as a student. Upon graduation, he took a job in Stalino (now Donetsk) in the Donets Basin. In the 1930s he changed careers and began writing full-time, publishing a number of short stories and several novels.
At the outbreak of the Second World War, Grossman was engaged as a war correspondent by the Red Army newspaper Krasnaya Zvezda; he wrote first-hand accounts of the battles of Moscow, Stalingrad, Kursk, and Berlin. Grossman's eyewitness reports of a Nazi extermination camp, following the discovery of Treblinka, were among the earliest accounts of a Nazi death camp by a reporter.
