His sibling was Tatyana Mavrina[1], and his child was Natalja Lebiediewa[4]. He was buried at Novodevichy Cemetery[5][4][1].He worked as a computer scientist, inventor, university teacher, and engineer in the field of computers[1][4]. Lebedev was educated at the Bauman Moscow State Technical University and the Moscow Institute of Physics and Technology[1]. His employers included the Bauman Moscow State Technical University from 1928 to the present, the All-Russian Electrotechnical Institute from 1928 to 1936 and again from 1936 to 1946, and the NASU Institute of Electrodynamics from 1947 to 1951[4][1].A member of the National Academy of Sciences of Ukraine and the Academy of Sciences of the USSR, Lebedev received multiple awards during his lifetime. These included the Medal "For Valiant Labour in the Great Patriotic War 1941–1945", the Order of the Red Banner of Labour, the Stalin Prize, the Hero of Socialist Labour, and the Order of Lenin, plus two more[1][4][6].

## Summary
Sergey Alexeyevich Lebedev (1902–1974) was a pioneering Soviet computer scientist and engineer regarded as the founder of the Soviet computing industry. He is most famous for leading the development of the MESM, the first universally programmable electronic computer in the Soviet Union and continental Europe, and for his long-standing leadership of the Institute of Precision Mechanics and Computer Engineering.

## Biography
- **Born:** November 2, 1902, in Nizhny Novgorod

## Contributions
Sergey Lebedev was the primary architect of the Soviet Union's transition into the digital computing age. His most notable early work was the creation of the **MESM** (Small Electronic Calculating Machine) between 1947 and 1951 while serving as the director of the NASU Institute of Electrodynamics in Kyiv. This machine represented the first universally programmable electronic computer in the region.

Following the success of the MESM, Lebedev moved to Moscow to lead the Institute of Precision Mechanics and Computer Engineering (IPMCE). Under his direction from 1953 to 1973, the institute developed the **BESM** (Large Electronic Calculating Machine) series. His work on the **BESM-6** was particularly significant, earning him the USSR State Prize in 1969. He also led the development of the **RZ-25**, for which he received the Lenin Prize in 1966. Beyond hardware design, Lebedev was a prolific educator, heading departments at the Moscow Power Engineering Institute and the Moscow Institute of Physics and Technology, where he mentored future leaders in the field such as Lev Nikolayevich Korolyov and Aleksandr Tomilin.

## FAQs
### Q: What is Sergey Lebedev's most famous invention?
A: Lebedev is best known for the MESM, the first universally programmable electronic computer in the Soviet Union. He also led the development of the BESM series, which provided the high-performance computing power necessary for Soviet scientific and industrial projects.

### Q: Why is the Institute of Precision Mechanics and Computer Engineering named after him?
A: The institute was renamed the Lebedev Institute in his honor because he served as its director for twenty years (1953–1973) and transformed it into the premier center for Soviet computer design.

### Q: What major awards did Sergey Lebedev receive?
A: He received the highest honors of the Soviet Union, including the title of Hero of Socialist Labour (1956), the Stalin Prize (1950), the Lenin Prize (1966), and the USSR State Prize (1969). Posthumously, he was honored with the 1996 Computer Pioneer Award.

## Why They Matter
Sergey Lebedev is the central figure in the history of Soviet computing. At a time when computing was transitioning from theoretical mathematics to physical hardware, Lebedev provided the engineering expertise to build functional, high-speed digital machines. His work allowed the Soviet Union to develop its own independent computing infrastructure, which was critical for its scientific, space, and military programs. 

By establishing the Institute of Precision Mechanics and Computer Engineering as a leading research hub, he created a legacy of hardware innovation that lasted for decades. His influence extended into academia, where he shaped the curriculum for computer science at the Bauman Moscow State Technical University and the Moscow Institute of Physics and Technology. His students and colleagues continued his work, ensuring that his architectural concepts influenced multiple generations of Soviet supercomputers.
