Dmitry Konstantinovich Bobylev was born in the Kharkov region of today's Ukraine. He graduated in 1862 from the Mikhailov Artillery Academy in Saint Petersburg and from 1871 taught physics at the University of Saint Petersburg and the Saint Petersburg Transportation Institute. He became in 1878 an extraordinary university professor and in 1885 was promoted there to full professor.

\

Bobylev's principal works are in the fields of hydrodynamics, electricity and magnetism. He studied in 1881 the pressure exerted by the flow of unlimited width on an equal side wedge. This problem was later also investigated by Ivan Vsevolodovich Meshchersky (1859-1935), who thereby analyzed the mathematical behavior of the equations and determined the pressure distribution as a function of the wedge angle relative to the attack of the flow. Both Bobylev and Meshchersky therefore continued their works in the lines of Hermann von Helmholtz (1821-1894), the founder of the mathematical theory in inviscid discontinuous fluid flow in the 1860s. Aleksander Mikhailovich Liapunov (1857-1918) wrote his first independent scientific works under the guidance of the mechanics professor Bobylev. Bobylev was in Russian one of the creators of analytic mechanics, based on Joseph-Louis Lagrange (1736-1813) and Ostrogradsky. He authored the major study "A course in analytical mechanics" published in four volumes between 1880 and 1884. Bobylev was elected corresponding Member of the Saint Petersburg Academy of Sciences in 1886.
