Andrey Nikolaevich Tikhonov (1906–1993) - mathematician, founder of the Faculty of Computational Mathematics and Cybernetics of Moscow University, Academician of the Academy of Sciences of the USSR, twice Hero of Socialist Labor, was born on October 30 in Jatsk. Already at the age of thirteen, the future scientist worked as a railway clerk, and received an education in various courses in the evenings. After passing the exams as an external student, in 1922 he entered the Faculty of Physics and Mathematics of Moscow University and graduated in 1927; From 1929 he worked at the Geophysical Institute, where he headed the Department of Mathematical Geophysics. In 1930, Andrey Nikolaevich completed his master's degree at the Research Institute of Mathematics at the University of Moscow and remained teaching. In 1937 he headed the Department of Mathematical Geophysics at the Institute of Theoretical Geophysics of the Academy of Sciences of the Soviet Union, which was created at the initiative of O.Yu. Schmidt. In the years before the war a. N. Tikhonov was involved in calculating the passage of a gas-air mixture through an absorbent material to create new gas mask systems, as well as in determining the historical climate of the Earth. In 1936 he defended his doctoral thesis "On functional equations of the Volterra type and their applications to the equations of mathematical physics", and in 1939, at the age of 33, he was elected a corresponding member. USSR Academy of Sciences. With the beginning of the war, the Tikhonov family was evacuated from 1941 to 1943 to Kazan. There Andrei Nikolaevich was engaged in exploration geophysics - he developed seismic and electrical search methods for oil exploration in the Volga and Ural regions. It was this work with inverse problems that later led him to create regulation theory, a scientific direction that gained worldwide recognition. In 1948, Tikhonov was drawn to the atomic project: he organized Computer Laboratory No. 8 for explosion calculations, and under his leadership, together with A. A. Samarsky in 1949 was the first to perform a direct calculation of an atomic explosion. A. N. Tikhonov founded and headed the Faculty of Computational Mathematics and Cybernetics of the University of Moscow, and was the director of the Institute of Applied Mathematics named after him. M.V.
