Cedric C. Jimerson was born in August 1919 in Hornby, NY. His father was a farmer who had graduated from Alfred College. In addition to working his 110-acre farm, he was head of the vocational shop at a high school in nearby Corning and was a home-builder. When Cedric was 13, his father died of tetanus, leaving his mother with four children under the age of 14. She began teaching for a dollar a day in one-room schools in the county and told the children they would have to work their way through college. Cedric proceeded to do just that, at Cornell University, and was one of seven students admitted to Cornell Medical College after his junior year. After graduating in 1943, he began his surgical training at The New York Hospital in New York City. His training was interrupted after his first year by military service, and he spent the next 2 ½ years as Captain and surgeon with the U.S. Army Medical Corps. He resumed formal training in 1946, first back at The New York Hospital in general surgery, then in thoracic surgery at the Bronx VA Hospital and at a VA hospital in upstate N.Y. Finally, he completed a senior resident year at New Britain General Hospital in New Britain, CT, followed by a 6-month pathology residency at the same institution.
