Hot Springs National Park has a rich history. The park has prehistoric American Indian novaculite quarries. It was the destination of the Dunbar-Hunter Expedition sent by President Jefferson in 1804. A bustling town grew up around the hot springs to provide services for health seekers. Central to the American Spa was the bathing industry. The Public Health Service Clinic that was in conjunction with the Government Free Bathhouse was one of the first facilities in the United States to use penicillin.
