A surgeon from Grand Rapids, Michigan, Frank Cammeron Kinsey was born 10 February 1877, in Ft. Wayne, Indiana, the son of Jacob J. Kinsey and Letitia H. Palmer. He died 31 July 1931, in Grand Rapids, Michigan. Kinsey received his education from the Grand Rapids public schools, University of Michigan and Northwestern University.

He was commissioned a lieutenant in the Medical Reserve Corps when the United States entered World War I. Soon after enlistment, Kinsey was promoted to captain. His military training was at Fort Oglethorpe, Georgia; Camp Sheridan, Alabama, and Camp Wheeler, Georgia. In late July 1918 Base Hospital 80 from Camp Wheeler, including Kinsey, shipped to Europe on Agamemnon, which docked at Brest in early August. At Brest, Base Hospital 80 was broken into separate units. Kinsey, with Teams 215 and 216, saw service near Verdun, just a few miles from the front lines. During this period Kinsey was promoted to major.

Following the armistice, Kinsey was in charge of the camp hospital outside of LeMans and later of the camp hospital at Ballon (just outside of Tours). In July 1919 Kinsey shipped back to the United State on President Grant, landing at Boston. He was discharged at Camp Dix on 15 July 1919. Following his discharge from active service, Kinsey was promoted to lieutenant colonel in the Medical Reserve Corps. He returned to Grand Rapids and reestablished his medical practice.

On 5 July 1920, in New York, Kinsey married Marie Louise Cosson, a native of LeMans. The Kinseys returned to Grand Rapids where they lived until Kinsey died. They had no children; the widow returned to France after Kinsey's death.
