The first female Indian physician, Susan La Flesche was born into the Sioux in 1865 and graduated from the Women's Medical College of Pennsylvania. She administered to Native American tribes, traveling on horseback from her home in Omaha, Nebraska. Eventually La Flesche became a Presbyterian missionary, heading a delegation to the nation's capital to fight for the prohibition of liquor. She died at age 50 in 1915, having spent her life in the service of her people. The symbol depicted at the bottom of the picture represents an Indian goddess against disease.
