William Castle DeVries (born December 19, 1943) is an American cardiothoracic surgeon, mainly known for the first transplant of a TAH (total artificial heart) using the Jarvik-7 model. Early years and Medical School William DeVries was born December 19, 1943, in Brooklyn Navy Yard. His father, Henry DeVries, was a Dutch immigrant who died in combat on the destroyer in 1944 during the Battle of Hollandia, where he had enrolled as a naval surgeon. When his father died William was only six months old. He was raised by his grandmother and his mother who was a member of the Church of Jesus Christ of Latter-day Saints until he was five.

He graduated in 1966 with a bachelor's degree in molecular and Genetic biology. Later on he went to medical school also at the University of Utah and received his M.D. degree in 1970.
