Semion Bliumenkrants was born in 1914 in Kremenchug, Ukraine. In the mid-1930s, he was qualified as a construction engineer and worked at the Moscow-based Chief Directorate of the Northern Sea Route. According to some sources, in 1938, during Stalin's "purges" of this directorate, Bliumenkrants lost his job. However, instead of being executed, he was deported to the Soviet Far East. From 1938 to 1941, he worked in the Soviet Far East and in the Kolyma region (in the Soviet Arctic) as an employee of the NKVD (precursor of the KGB) Administration for Dalstroi (abbreviation for Far Eastern Construction).
With the beginning of the Soviet-German war in June 1941, Bliumenkrants was drafted into the Red Army. After starting as an infantryman, he was sent to officers' school. After graduating, Bliumenkrants served as a staff officer in various units. In 1942 and 1943, he took part in the Stalingrad operation. On January 31, 1943, as chief of staff of the 1,326th Infantry Regiment, Captain Bliumenkrants accepted the surrender of the German Lieutenant-General Alexander Edler von Daniels, the commander of the Wehrmacht's 376th Infantry Division. Following the end of the Stalingrad operation, Bliumenkrants was awarded the Order of the Patriotic War, 2nd Class. During the following years, he took part in the Kursk Salient operation (during which he was wounded), and in battles in Romania and Hungary. Despite his being a staff officer, more than once, he took part in a combat. In January 1945, he was wounded again. By the end of the war, Lieutenant-Colonel Bliumenkrants had been awarded four military orders.
After the war, Semion Bliumenkrants continued in army service. He retired in the 1960s and settled in Riga, Latvia, where he continued to work at his previous profession of construction engineer. He died in 1989.
