Dallas-based architect Roscoe P. DeWitt graduated from Dartmouth in 1914 and received his MA in architecture from Harvard in 1917. DeWitt was a veteran of both world wars and served during World War I as a Captain with Battery E of the Fifty-Eighth Artillery in the Coast Artillery Corps. Following World War I, he began his career as a prominent Dallas architect, first partnering with Mark Lemmon (1921–1927). Their firm designed Sunset High School, Woodrow Wilson High School, several projects at Southern Methodist University, and the main sanctuary for Highland Park United Methodist Church.[1]

During his World War II service, DeWitt was transferred to the MFAA due to his architectural background and while in France, he was part of the MFAA team inspecting and safeguarding historical buildings throughout the countryside.

After World War II, DeWitt joined forces with Arch B. Swank and their architectural firm DeWitt and Swank “emerged as one of the most successful in Texas after the war.”[2] DeWitt designed buildings at Parkland Memorial Hospital in Dallas, two Neiman Marcus stores (as well as Stanley Marcus’ home in 1937), St. Vincent’s Medical Center in Jacksonville, Florida and several public housing projects in the Dallas area. Among numerous other projects, DeWitt participated in the restoration of the original Senate and Supreme Court chambers and the James Madison Memorial Building of the Library of Congress in Washington, D.C.

DeWitt served on the board of directors of the Dallas Civic Opera as well as on the advisory board for the Texas Commission on Arts and Humanities. He was a member of the Dallas Historical Society, Texas Philosophical Society, Royal Society of Arts, the American Federation of the Arts, the Harvard Club of New York and the Cosmos Club of Washington, D.C. DeWitt died on November 2, 1975 leaving a lasting legacy for the city of Dallas.
