Dr. Smith's Champion Hoss Hair Pullers were an American old-time string band. Dr. Smith’s Champion Hoss Hair Pullers was founded by Dr. Henry Harlin Smith, a surgeon for the Missouri Pacific Railroad who lived in the Calico Rock (Izard County) area. On his travels with the railway, he found that he was often working to dispel the backward image that many people outside of Arkansas had of the region. Smith thought that if more people were to visit Calico Rock and enjoy the area’s natural beauty, it could change the negative misconception that was so prevalent.
