Early life and education
Knowles was born on May 23, 1926, in Chicago to James Knowles (1896–1971), who was a flying ace in World War I and served as vice president of the Rexall Drug Company, and Jean Laurence Turnbull (1894–1982), an artist. Knowles grew up in Normandy, but when he was twelve he and his family moved to Belmont where he would attend Belmont High School. After graduating from high school, Knowles would enroll at Harvard College where he majored in biochemistry. Along with his classmate Jack Lemmon, he would play piano on the Harvard radio station. He graduated in 1947 completing his Bachelor of Arts. After being rejected by eleven medical schools, including the Harvard Medical School, he would enroll at the Washington University School of Medicine where he would be elected into the honor society Alpha Omega Alpha and graduated cum laude as Doctor of Medicine.

Knowles would start his medical internship at the Massachusetts General Hospital where he would meet Edith Morris LaCroix, a cytotechnologist, whom he would marry in 1953 and have six children with.
