Lev Razumovsky was born in Leningrad and had completed 7 grades of secondary school by June 1941, when Nazi Germany invaded the Soviet Union. He very nearly died during the first winter of the Leningrad siege, but survived, in his own words, "thanks to the courage, kindness, and саrе of my family." In August 1942, he was evacuated with an orphanage where his mother and sister worked, to a village in central Russia.
He was drafted to the army in 1943 at the age of 17, seriously wounded at the front line in 1944, losing his left arm and spending 10 months in hospitals.
After the war he entered Mukhina College of Art and Design to become a sculptor. He studied there for eight years, as did all students of the postwar generation, to catch up with basic school subjects. His diploma work, the Pilot (cast bronze,1953) was installed in Victory Park in Leningrad (now St. Petersburg), and is still there today.
In 1955, Lev was admitted to the Union of Artists of Russia. In sculpture, he worked in various genres: monuments, park sculpture, portraits, compositions, small-size sculpture, and medals. War and the Holocaust were major themes in his work.
Lev was also a professional toy designer: his models were produced in large quantities by toy factories of Leningrad and Moscow, and have been loved by several generations of children.
His memoirs about bitter experiences during the siege and in the Soviet army were published in the 1990s. He also wrote about 100 short stories.
Lev Razumovsky took part in numerous exhibitions – local, national and international. His works are displayed in Russian museums and in private collections in Russia, Finland, Sweden, Denmark, the Netherlands, Germany, Hungary, Israel, and the US.
