Malcolm MacLeod Atterbury was an American stage, film, and television actor, and vaudevillian.

William Wallace Atterbury was a brigadier general in the United States Army during World War I, who began his career with the Pennsylvania Railroad (PRR) in 1886 and rose through the ranks to become its tenth president (1925–1935). As director-general of transportation in France during the war, the New Albany, Indiana, native and Yale University graduate was instrumental in reorganizing railroad traffic for more efficient transportation of troops and supplies for the American Expeditionary Forces. He was also known as "The Railroad General". Under his leadership after the war, the Pennsylvania Railroad undertook a $250 million project to electrify major portions of its main line that ran between New York City and Washington, D.C. He also assisted in development of the company's first M1-class steam locomotive.
