Stapleton, Denver the A Line. The original airport was named for Benjamin Franklin Stapleton (November 12, 1869 – May 23, 1950) who was the Mayor of Denver for two periods (comprising five terms), the first from 1923 to 1931 and the second from 1935 to 1947. He also served as a high-ranking member of the Ku Klux Klan and the Democratic Colorado State Auditor from 1933 to 1935. Today, the Stapleton neighborhood continues to bear his name despite increasing political pressure to rename it due to Benjamin Stapleton's adherence to white supremacy and membership in the Ku Klux Klan.
