V.M. Lihin (1846–1900), as historian of science and technology

The main purpose of the article is the coverage of the little-known facts of scientific activity of V.M. Lihin (1846-1900). A talented scientist and educator, an active social person, his work on mechanics and mathematics is widely known, but his works on the history of science and technology have not become widely publicized in the nineteenth century and almost lost during the twentieth century. Modern historical science has not considered this part of the scientific heritage of the mechanic from Odesa. Some scholar's works are presented for the first time.
