George Albert Flippin (February 8, 1868 – May 15, 1929) was an American football left halfback and a medical doctor in Nebraska.
[4] Flippin's father, Charles, was a freed slave who fought in the Civil War on the Union side in the 14th United States Colored Infantry Regiment, then became a doctor.
He was denied entrance to an opera house after a game in Denver, and he sued a bathhouse in Lincoln for refusing to admit him because of his race.
A restaurant in Omaha relegated the football team to a private dining room rather than allow Flippin to be seen in the public area.
[3] Flippin left Nebraska to study medicine at the College of Physicians and Surgeons in Chicago from 1898, graduating in 1900.
