Nikoloz Muskhelishvili
Nikoloz (Niko) Muskhelishvili (; – 15 July 1976) was a renowned Soviet Georgian mathematician, physicist and engineer who was one of the founders and first President (1941–1972) of the Georgian SSR Academy of Sciences (now Georgian Academy of Sciences). He is often referred by the Russian version of his name, Nikolai Ivanovich Muskhelisvili (Николай Иванович Мусхелишвили). Life and career. Muskhelishvili was born on in Tbilisi, then part of the Russian Empire into a family of engineers. He graduated from local grammar school in 1909 and afterwards from the Physics and Mathematics Faculty of Saint Petersburg in 1914. Immediately after his  graduation he became head of Applied Mathematics of the same faculty and in 1918 passed the exam for the master's degree. His first scientific magazine was published already earlier in 1915 containing a number of issues on elasticity theory. From 1917 to 1920 he worked as assistant director of the Petrograd University and also taught mathematics in other institutions in Saint Petersburg. At request of the short-lived Democratic Republic of Georgia he moved back to his native country in 1920 in order to organize the establishment of a national scientific school. There Muskhelishvili conducted lessons in the Tbilisi  State University and Polytechnic Institute as an assistant professor and from 1922 to 1938 as head professor. After the Soviet invasion of Georgia in 1921, Muskhelishvili was allowed to carry on his works in the Transcaucasian Soviet Academy of Sciences and since 1933 was corresponding member of the USSR Academy of Sciences. He became a member of the CPSU in 1940. In 1941 based on the former Georgian Academy of Sciences a new USSR Academy of Sciences was established by the Georgian SSR and Muskhelishvili got elected as its first president and academician. Simultaneously he also became director of the  Tbilisi Mathematics Institute named after AM Rasmadze, and held that position until his death in 1976. From 1956 to 1976 Muskhelishvili was chairman of the National Committee of the USSR on Theoretical and Applied Mechanics (established by the Decree of the Presidium of the Academy of Sciences). Since 1957 he was also member of the Presidium of the Academy of Sciences. In 1972 due to health problems the professor resigned from the post of president of the Georgian SSR Academy of Sciences but in recognition for his outstanding achievements and services was elected honorary president of the academy. He was  also an academician and honorary professor of the Academies of Sciences of the Armenian and Azerbaijani SSRs since 1961. Muskhelishvili was an honorary member of the Bulgarian Academy of Sciences since 1952, Polish Academy of Sciences since 1960 and the Berlin Academy of Sciences since 1967. He also held the position of deputy chairman of the Supreme Soviet of the Soviet Union in eight convocations from 1937 to 1974. Nikoloz Muskhelishvili died on 15 July 1976 in Tbilisi and is buried in the Mtatsminda Pantheon. Contributions to science. Muskhelishvili conducted fundamental research on the theories of physical elasticity, Integral equations , Boundary value problems and other. He was one of the first to apply the theory of functions of complex variables to the problems of elasticity theories, proposing a number of techniques that have been successfully implemented in numerous areas of mathematics, theoretical physics and mechanics. His works solved all major problems of the Plane Elasticity Theory opening a wide class of domains reducing the plane problem to finite systems of linear algebraic equations c singular kernels. He is also credited with major contributions to the theory of linear boundary value problems for analytic functions and one-dimensional integral equations. Muskhelishvili  is the author of various scientific articles, monographs and textbooks on mathematics which have been used by universities since their publishing. Highest regarded ones are the monographs "Some basic problems of the mathematical theory of elasticity" (1933) and "Singular Integral Equations" (1947). Involvement in military research. During World War II Muskhelishvili was responsible for retargeting the preoccupation of the Academy of Science to national defense. He completed a series of research, experimental and theoretical work in different areas of applied mathematics, physics and mechanics, which all had great practical importance and decisive impact on the development of a range of  military hardware during and after the war. However, the exact scale is unknown and classified. His achievements and involvement in the defense sphere earned him several awards, including the Medal "For the Defence of the Caucasus". He got also awarded for the launch of the world's first artificial satellite into space in 1961 on which development he had contributed as well. Muskhelishvili was a renowned specialist in engineering able to apply a lot of his theories and solutions, including torsion bar suspension for tracked vehicles such as tanks. Most of his research, theories, and ideas were considered and implemented  for the development of certain vehicles during the Cold War, some of which already originated from his earlier theoretical work during World War II, on the elasticity of specific material under specific circumstances such as different temperature, weight, composition etc. His work practically applied to anything from land-based vehicles to aircraft, rockets, and satellites. Notable awards. The Georgian Academy of Sciences established a prize named after Nikoloz Muskhelishvili.
