Edward Hartley Angle (June 1, 1855 – August 11, 1930) was an American dentist, widely regarded as “the father of American orthodontics“.[1] He was trained as a dentist, but made orthodontics his speciality and dedicated his life to standardizing the teaching and practice of orthodontics. He founded the Angle School of Orthodontia in St. Louis and schools in other regions of the United States.
