Peter V. Karpovich (1896-1975) was born in Russia and trained as a medical doctor at the State Military Academy of Medicine in Petrograd (St. Petersburg), Russia in 1919.

In 1927, while completing his studies, he became a professor of physiology at the college. In the late 1940s, he met and married his second wife, Josephine Rathbone, an acclaimed scholar of physical education and relaxation. From 1961 to 1969, he served as the director of the physiology research laboratory at Springfield College, where he published several seminal books. Karpovich was a founding member of the American College of Sports Medicine and a consultant to many government, private and educational organizations. He remains an internationally recognized pioneer in physical education.
