ADA History

The ADA Timeline provides a chronological and historical representation of the American Dental Association from 1859-2009. The first president of the American Dental Association, pictured on the left, was William Henry Atkinson (1815–1891). He served the ADA from 1860-1861 and again from 1861-1862. Atkinson originally trained as a physician, but later became interested in dentistry and the opportunities it offered at that time for a young man starting a practice.

He had prominent practices first in Cleveland, OH and later in New York City. He was a well known scholar and clinician of his era and was a frequent contributor of articles to the dental literature. His diverse interests included microscopy and the study of the natural sciences, diagnosis, physiology of the blood, alveolar abscess, decalcified teeth, dental therapeutic agents, dentures and the relation of general to specific practice.   

Since its founding in 1859, there have been 150 presidents of the American Dental Association. Each of these individuals represented some of the best in the profession and the list of ADA presidents (PDF) reads as a who’s who of the history of dentistry. Among the better known are G. V. Black and Thomas Hinman.   

If you are interested in finding out more on the history of the dental profession, visit the ADA Library & Archives, or call the Archives of the American Dental Association (312-440-7722, or the members-only 800#, x7722).
