Edward H. Angle


Edward H. Angle was an American dentist and founder of modern orthodontics. Angles dedicated his life to standardizing the teaching and practice of orthodontics. He founded the Angle School of Orthodontia in St. Louis, MO in 1900. Charles Harold Tweed, a Phoenix, AZ orthodontist, revolutionized the profession of orthodontics with a technique involving the use of traction and multiple wiring devices in tooth arrangement.

The collection includes letters and telegrams of Edward H. Angle and Ann Hopkins Angle (the first lady of orthodontics) to Charles Harold Tweed relating to the practice of orthodontia and to dental legislation in Arizona. Includes biographical data by Bernard L. Fontana and portraits.
