N. N. Polyakhov (1906-1987), Doctor of Engineering Science,  Professor. Honoured Scientist of the Russian Federation. He graduated from Moscow University, in 1929-1941 worked at Zhukovskii Central Aerohydrodynamic Institute under supervision of academician S.A. Chaplygin, he and V.P. Vetchinkin developed a mathematical model of marine screw propeller. In 1953-1978 he   headed the Chair of Theoretical and Applied Mechanics at the Faculty of Mathematics and Mechanics of Leningrad University. Under his supervision there was written the textbook “Theoretical Mechanics”, which was awarded the First premium of Leningrad University in 1987. N.N. Polyakhov was awarded a number of orders and medals, among them two Orders of Lenin, which was the highest decoration bestowed by the Soviet Union.
M. P. Yushkov, Dr. Sci. in Physics and Mathematics, Professor. He graduated from the Faculty of Mathematics and Mechanics of Leningrad University in 1957 and completed a post-graduate course at the Chair of Theoretical and Applied Mechanics. Since 1960 till now he has been working at this Chair. In 1987 he became a Laureate of the First premium of Leningrad University, and in 2011 he was awarded the Prize of Saint Petersburg State University  “For scientific works”.  He is a co-author (and partially a responsible editor) of four monographs  on nonholonomic mechanics, one of them being translated into Chinese, and another being published in English by Springer Publishing Company. He is awarded a few medals and the Russian Federation Presidential Certificate of Honour and has got the title “Honorary Professor of Saint Petersburg State University”.
