Clarkson was born in New York City on July 15, 1926. He is the son of the wealthy banker, Robert Livingston Clarkson Sr. (1892–1969), who was the president of Chase National Bank from 1928 to 1929. R. L. Clarkson Sr. and his wife Cora G. Clarkson née Shields (1897–1981) had two other sons, Robert Livingston Clarkson Jr. (1924–1965) and Peter Schuyler Clarkson (1930–1950). The Clarkson family is related to Matthew Clarkson (1758–1825) and is connected to Clark University.[1][2] When the attack on Pearl Harbor occurred, Bayard Clarkson was attending New Hampshire's St. Paul's School. In December 1943 he enlisted in the U.S. Navy's aviation program. However, he was diagnosed with inactive tuberculosis and judged ineligible for active duty. Thereupon, he joined the American Field Service (AFS). In the summer of 1944, AFS sent him orders for two weeks of basic training, after which he was sent overseas in August 1944. From early September 1944 through March 1945 he served in Italy with Unit CM 90 of the AFS. In the spring of 1945 he volunteered for service in the evacuation of Bergen-Belsen concentration camp. In July 1945, he shipped out from Copenhagen. In autumn 1945 he matriculated at Yale University.[1]
After graduating from Yale, Clarkson studied medicine at the Columbia University College of Physicians and Surgeons, where he graduated with an M.D. in 1952. At New York Hospital (now called Weill Cornell Medical Center), he served his medical internship and residency[3] in endocrinology and hematology.[4] In 1958 he became a Special Lasker Fellow in Clinical Chemotherapy at (what became in 1960) the Memorial Sloan Kettering Cancer Center (MSKCC), where he continued working and coauthoring articles[5] until 2017.[6] AT MSKCC he became in 1970 the Chief of the Hematology Service and in 1980 the Enid A. Haupt Chair of Therapeutic Research. He was from 1975 to 1989 the MSKCC's Chief of the Hematology/Lymphoma Service.[5]
