Pelham Davis Glassford (August 8, 1883 – August 9, 1959) was a United States Army officer who attained the rank of brigadier general during World War I. He later served as Superintendent of the District of Columbia Police Department, and was in large measure held responsible for the violence that ended the 1932 Bonus Army protests. During World War I, Glassford directed two artillery schools in France, commanded a Field Artillery regiment, and then commanded a Field Artillery brigade. He was promoted to brigadier general in 1918, and was the Army’s youngest general officer at the time.
