After receiving a Bachelor of Arts degree from Harvard College in 1908, King attended at the Columbia University School of Architecture in New York and then went to Paris for study at the Ecole des Beaux-Arts. Upon his return he entered the New York firm of McKim, Meade and White.
Following World War I, during which King served in United States Army Intelligence in France, he became a founding partner in the New York architectural firm Wyeth and King. The firm designed several prominent buildings in that city, among them the Osborn residence on East Seventieth Street; the Woman's National Republican Club; and the Church of the Epiphany. A prominent member of a family that traced its ancestry to Peter Stuyvesant, King was an active member of several important organizations; he was a trustee to Barnard College, Columbia University, and of the New York Society Library.
