Medical College of Pennsylvania actually existed and is today part of Drexel University College of Medicine. The Sand Creek Massacre in 1864 was referred to in the pilot episode (though it was historically inaccurate as the pilot took place in 1867). Lieutenant Colonel George Armstrong Custer, and Chief Black Kettle, are true historical figures. The Battle of Washita River, seen in the third-season episode "Washita," was an actual historical event. In the show, the battle took place in 1869 in Colorado, while in fact it took place in the fall of 1868 in Oklahoma. People have often asked if Dr. Michaela Quinn was based on a historical person, such as Dr. Susan Anderson. In an interview in September 2013, the show's creator, Beth Sullivan, said that she knew nothing of real women doctors at that point in history. CBS asked her to create a family drama for the eight o'clock time slot and she asked if it could be a female lead in a period piece and they said yes. She said she had always been interested in the post-Civil War period and the rest came from her imagination, giving the character of Dr. Michaela Quinn her own world view. In what most consider the final episode of the series, the town's often-antagonist banker, Preston A. Lodge III, went bankrupt as a result of the great stock market crash, caused by the Panic of 1873, a historically-accurate event. Lodge lost much of the townspeople's money along with his own, in the Panic. The episode "The Body Electric" features Walt Whitman, who was a poet and a true historical figure. One of the major historical oversights of the show is that Colorado Springs was not technically founded until 1871, by General William Palmer, and was mainly a resort town. There were no saloons, as Palmer declared Colorado Springs to be alcohol-free. Colorado Springs stayed "dry" until the end of Prohibition in 1933. However, nearby towns, including Old Colorado City and Manitou Springs did permit saloons. In the episode "For Better or Worse: Part 1", the folk song “I’ve Been Working on the Railroad” was played by the brass band; the song was not written until 1892. Dr. Quinn was largely filmed at the western set on Paramount Ranch in Agoura Hills. Fans of the show were able to visit the sets, talk to the actors, and watch episodes being shot during
