Georgy Ionovich Kruchkovich – An Outstanding Scientist, Methodist, Head of the Department of Higher Mathematics at VZEI – MIREA (On the 100th Anniversary of His Birth)

April 3, 2025 is the 100th anniversary of the birth of the Russian mathematician, a prominent specialist in the field of multidimensional differential geometry, a talented organizer of educational and scientific processes in the work of the mathematical department of a technical university, a participant of the Great Patriotic War, Doctor of Physical and Mathematical Sciences, Professor Georgy Ionovich Kruchkovich (1925-1985). For 20 years the scientist headed the Department of Higher Mathematics: the All-Union Correspondence Energy Institute (VZEI) for two years (June 1965 - June 1967), which was later renamed the Moscow Institute of Radio Engineering, Electronics and Automation (MIREA), for 18 years (June 1967 - July 1985). He is the author and co-author of textbooks, which were used and recognized as the best by students of correspondence, evening and full-time departments of technical universities of the Soviet period. But these books have not lost their relevance to this day. The name of the scientist is very rarely mentioned in studies of historical and mathematical character. The purpose of this article is to eliminate this injustice. The article provides little-known information from the biography of G.I. Kruchkovich, reconstructs his scientific and methodical achievements, describes his public, educational and organizational work as head of the Department of Higher Mathematics, as well as his scientific and pedagogical heritage.
