Dmitri Ilyich Kozlov

Kozlov fought the Nazis in the Second World War, losing his left arm. In the 1950s he worked under Sergey Korolyov and was in charge of designing the R-7 missile. As a leading designer of intercontinental ballistic missiles Kozlov was awarded a Lenin Prize (1957), two USSR State Prizes (1976, 1983), a Russian Federation State Prize (1994) and was named a Hero of Socialist Labour on two occasions (1961, 1979).

In May 1946, he worked at Plant No. 88 of the Ministry of Armament of the USSR in Kaliningrad on the development of long-range guided ballistic missiles. Starting in June 1951, he worked at OKB-1 of the State Committee of the Council of Ministers of the USSR for Defense Equipment in Kaliningrad where he became the lead designer of the R-5 ballistic missile and the world's first intercontinental ballistic missile: the R-7. In April 1958, he became the Deputy Chief Designer of OKB-1 responsible for the mass production of the R-7 missile in Kuibyshev. In January 1961, Dmitry led the design of the first two stages of what would become the launch vehicle of the Vostok spacecraft, which enabled Yuri Gagarin to make the world's first human flight to outer space. After 1967, Dmitri led the development of a number of Soviet satellites that studied ecology, mapping and space research. From 1983, he was the Central Specialized Design Bureau head and general designer. In 1996, he was the General Designer of the Progress program. He retired in 2003.

After Dmitri returned to the Leningrad Military Mechanical Institute, he graduated in December 1945. In 1946, he studied at a special course at the Moscow Higher Technical School. In June 1946, he worked as part of a technical commission to study the captured rocket technology from Germany when he met Sergey Korolyov.

While in the Leningrad Peoples Militia, he was wounded in August 1941 in the battles near Luha. After recovering from his wounds, he enlisted in the Red Army's 165th Construction Battalion of the 2nd Shock Army on the Volkhov Front. He became a second lieutenant in November 1943 and by the end of 1943, he was the platoon commander of the 71st Separate Marine Rifle Brigade. During the Leningrad-Novgorod offensive operation (January–February 1944), he was seriously wounded for a second time. During the Vyborg offensive operation on July 12, 1944, he lost his left arm. In September 1944, he was finally demobilized for his disabilities, so he returned to his education.

Dmitry Ilyich Kozlov (1 October 1919, Tikhoretsk – March 7, 2009, Samara) was a Russian aerospace engineer who founded the Progress State Research and Production Rocket Space Center.

Dmitry was born on October 1, 1919 in the village of Tikhoretskaya in the Caucasian Department of the Kuban Region (now Tikhoretsk, Krasnodar Krai, Russia). His father worked in railway transport so he moved schools frequently. He studied in Vladikavkaz, Grozny, Novorossiyk and finally graduating from high school in Pyatigorsk in 1937. He'd hoped to be a sailor, but was not accepted into naval school due to his poor eyesight. In 1937 he enrolled the Leningrad Military Mechanical Institute until his fifth year when he enrolled in the Leningrad People's Militia in 1941 on the outbreak of World War II.
