Dr. Otto U King

Otto Ulysses King (1873–1951) was an American dentist from Huntington, Indiana and the first General Secretary and Editor of the American Dental Association in 1913–1927.

As a dentist, King had multiple accomplishments and positions within the United States. He was Indiana State Dental Association President. He was elected as General Secretary of the National Dental Association, currently known as the American Dental Association.

King was also a member on Committee on Dentistry, which was part of the General Medical Board of the Council of National Defense for World War I. He used the Journal of the American Dental Association to advertise membership and promote support for the war efforts. King emphasized dental hygiene to ensure the prevention of disease. He is quoted to have said that "socialized health" should combat "capitalist disease" and emphasized the need for free dental health care clinics.

In 2018, a historical marker was erected in Huntington, Indiana to honor King's accomplishments in modern dentistry.
