Konstantin Zworykin — a direct ancestor of Renat Besolov on the maternal line, founder of the science of metal cutting
A Russian engineering technologist who in 1893 laid the scientific theory of metal cutting. Professor, dean and director (rector) of the Kyiv Polytechnic Institute. Uncle of Vladimir Zworykin — the “father of television.”
Creator of the scientific theory of metal cutting
Konstantin Alekseevich Zworykin was born on 25 March (6 April) 1861 in Murom, into the Zvorykin merchant family. In 1884 he graduated from the St. Petersburg Technological Institute; in 1885-1887 he designed ship mechanisms in Astrakhan.
From 1888 he taught at the Kharkiv Technological Institute (courses in flour milling and wood technology), and from 1894 was a full professor. In 1898, at the invitation of V. L. Kyrpychov, he moved to the Kyiv Polytechnic Institute.
In 1893 he published a classic work on the work and forces in metal cutting, laying the scientific theory of cutting. He theoretically determined the position of the shear plane discovered by I. A. Time, and designed a self-recording hydraulic dynamometer to measure cutting forces.
At KPI he was dean of the mechanical department (1898-1904), director and rector of the institute (1904-1905), and in 1922-1927 headed the research department of mechanical technology. He became the founder of KPI's world-famous scientific school of metal cutting. Actual State Councillor (1904). He died on 7 July 1928 in Kyiv.
The Zvorykin family — direct maternal line
The line from Konstantin Zworykin to Renat Besolov runs through Renat's great-grandmother, Milica Zvorykina. Konstantin Zworykin's biography is confirmed by encyclopedic sources; the degrees of kinship within the family are given per family records.
