Paul Ward Beck (1 December 1876 – 4 April 1922) was an officer in the United States Army, an aviation pioneer, and one of the first military pilots. Although a career Infantry officer, Beck twice was part of the first aviation services of the U.S. Army, as de facto head of the flying section of the Aeronautical Division, U.S. Signal Corps in 1911 and as a senior officer of the Air Service in 1920–1922. He is generally credited as being the first military officer to advocate an air force for the United States separate from the control of other branches of the Army.
