Miklós Steinmetz (1913—1944) was a Hungarian-born Soviet Red Army captain. His parents were communists, and, after the fall of the Hungarian Soviet Republic in 1919, the family fled to South America before immigrating to the Soviet Union. Steinmetz became a member of the Komsomol – the Soviet Communist Youth Organization, and then fought on the Republican side in the Spanish Civil War, becoming a captain in the Red Army during World War II.
