Yakov Ivanovich Sekerzh-Zenkovich graduated as a mathematician from the University of Moscow in 1924, and as a civil engineer in 1925. He gained his PhD title from the Moscow School of Mathematics and Mechanics in 1937 on a topic in differential equations and received the title Doctor of Sciences in 1957. Sekerzh-Zenkovich was from 1925 to 1941 a staff member of the Central Aero-Hydrodynamic Institute TsAGI, Moscow, and he was from 1942 to 1951 a senior scientific staff member of the Hydrophysical Laboratory of the USSR Academy of Sciences. Finally, from 1951 to 1985, he was attached to the Institute of Mechanical Problems of the USSR Academy of Sciences, Moscow.

Sekerzh-Zenkovich may be considered an important individual of theoretical mechanics of the 20th century. He is famous for works in elasticity, aerodynamics and fluid mechanics. In addition, his works in fluid waves are well known, because he solved an array of non-linear problems of mathematical physics as a boundary value problem. His doctoral thesis was entitled "Hydrodynamic research of waves of finite amplitude", a topic that had been investigated from the 19th century by great mathematicians of the caliber of George Biddell Airy (1801-1892) or George Gabriel Stokes (1819-1903). Sekerzh-Zenkovich published later also works on the stability of cylindrically shaped elements under bending conditions, on the aerodynamics of nonstreamlined bodies, and on the streamlining of thin bodies in the incompressible and weightless fluid. He was awarded a Medal for excellence in labor during World War II, a Medal in honor of the 800th anniversary of Moscow city in 1946, and the Order of Lenin in 1953.
