For several decades, George W. Hahn's 1955 classic account of "The History and Philosophy of the Edward H. Angle Society of Orthodontia" has been essential reading for every new or prospective or reflective member of the Angle Society. It is here reproduced in its original form, as published privately by the Society in 1956, with only minor typographical improvements. Wendell Wylie's salient preface for the original essay is retained in this electronic edition, as are the references to our Society under its former name, the Edward H. Angle Society of Orthodontia.Enjoy this inspiring historical portrait of the Angle Society. It is a proud heritage.
