Born to a Jewish family in Ukraine, then a 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. He began writing full-time and published a number of short stories and several novels. At the outbreak of the Second World War, he 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.
