The little-known facts from the life of Miron Semenovich as a teacher and a competent clinician are analyzed. It is shown that from 1936 until the end of his life he was the head of the Department of Internal Diseases of the CIU. During the Second World War (1941–1950), M.S. Vovsi was the chief therapist first of the Red, and then of the Soviet Army. The scientist has written about 60 scientific papers. Among them are monographs that are mainly devoted to research on the physiology and pathology of the kidneys, lungs, heart, and liver and military field therapy. The works of M.S. Vovsi on kidney diseases are widely known to domestic doctors. They have become manuals for practitioners of various profiles. Among them are the monographs «Acute nephritis», «Nephritis and nephrosis» (together with Professor G.F. Blagman), the manual «Diseases of the urinary system», «Clinical lectures», etc. He was the author of numerous journal articles and reports published in the following publications: Therapeutic Archive, Clinical Medicine, collections, proceedings of therapeutic congresses, etc. Every speech and publication in the press of Miron Semenovich was always met by practitioners and clinicians with great interest and attention.
