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
