Live and act
Angle was born on a farm in Pennsylvania , the fifth of seven children . More of a practitioner than a good student, Angle attended the Pennsylvania College of Dental Surgery , where he also graduated in the spring of 1876. After several years of hiatus because of his tuberculosis disease and engaged in sheep farming, he was appointed professor of histology and anatomy at Minnesota Hospital College, which later became the University of Minnesota , and was up to 1899 worked as professor of orthodontics at other universities in the USA. In 1885 Angle got a chair at the University of Minnesota. From 1892 to 1898 he was Professor of Orthodontics at Northwestern University , from 1886 to 1899 at the Marion Sims College of Medicine and from 1897 to 1899 at the Washington University Medical Department.
He married Florence in March 1887 and had a daughter, Florence Isabel, almost nine months later. After an unhappy marriage, he married Anna Hopkins (1872–1957), his long-time secretary, in 1908.
In 1900 he opened his own training institute, the Angle School of Orthodontia in St. Louis , Missouri .

In the years that followed, Angle developed and invented various orthodontic appliances. He developed an apparatus consisting of expansion bends and screw bands, the so-called angle bend. Historically, he introduced the concept of anchoring to orthodontics .
A quote from his book "Treatment of malocclusion of teeth" (Philadelphia 1887) at the beginning of the anchoring chapter:
- “The movement of one or more teeth in one of the different directions is only possible by applying a force that is in accordance with the laws of mechanics and dynamics. According to the well-known laws of physics, action and counteraction are balanced and opposed to each other; from this it follows that the resistance of the anchorage must be greater than that of the tooth to be moved. " Later he adds: " The ideal anchorage would of course be an immovable base. "
The relative positional relationship of the human upper and lower jaw is described worldwide according to Edward H. Angle by the Angle classes .
The orthodontic journal The Angle Orthodontist was founded in his honor in 1930 and has been the official organ of the Edward H. Angle Society of Orthodontists ever since and is published every two months.
