William Cramp Scheetz, Jr. was born in Bala Cynwyd, Pennsylvania, the son of architect
William Cramp Scheetz and Mary Wood. He attended Episcopal Academy in Merion, PA, and trained at the University of Pennsylvania, as had his father, earning a B.F.A. in 1934, followed by a B.Arch. (with honors) in 1935 and an M.Arch. in 1936. After completing his degree, he worked as a draftsman in the office of
George Howe until 1937, when he entered his father's firm,
Savery, Scheetz & Gilmour. It is not certain when he was made a partner, but this probably took place around the time of his father's death in 1945, since he joined the national A.I.A. in 1946. The firm endured until 1958, when
Douglas Gilmour left to form a partnership with
Fred Fretz Martin. Scheetz continued the practice of the firm under his own name until his retirement in 1980.
During World War II, Scheetz was as a lieutenant commander in the Navy, serving as a damage control officer. He was, among other affiliations, a member of the Pennsylvania Society for Promoting Agriculture, the Military Order of the Loyal Legion, the Military Order of Foreign Wars, and the Pennsylvania Sons of the Revolution.
