Sergey Borisovich Stechkin (Russian: Сергей Борисович Стечкин) (6 September 1920, Moscow – 22 November 1995, Moscow) was a prominent Russian mathematician who worked in theory of functions (especially in approximation theory) and number theory.

His father (Boris S. Stechkin) was a Soviet turbojet engine designer, academician. His great uncle, N.Ye. Zhukovsky, was the founding father of modern aero- and hydrodynamics. His maternal grandfather, N.A. Shilov, was a notable chemist.

Stechkin studied mathematics in Moscow State University, he was a student of D.E. Menshov. Stechkin received his Ph.D. in 1948, his thesis was titled “On the order of best approximations of continuous functions”.

Later he worked as a mathematician at Steklov Institute of Mathematics in Moscow. He was the founder and first director of the department of the Institute in Yekaterinburg. Later this department became the Institute of mathematics and mechanics of the Ural branch of the Russian Academy of Sciences.

Stechkin founded, and, for more than 20 years, headed as the editor-in-chief the mathematical journal “Mathematical Notes” (Russian: Математические заметки) [1].

Stechkin was a professor of mathematics in Moscow State University. His honors include Chebyshev Award of the Russian Academy of Sciences (1993)

His contribution to mathematics includes:

• generalization of Jackson's inequality for all L_p spaces.
