Clarence Gonstead

Clarence Selmer Gonstead (July 23, 1898 – October 2, 1978) was an American chiropractor.

[5] After his arthritis was cured by a chiropractor, he was motivated to enroll in the Palmer School of Chiropractic in Davenport, Iowa.

While Gonstead was a student, school president B. J. Palmer began promoting the neurocalometer (NCM), an invention of chiropractor Dossa Dixon Evins (1886–1932).

Over the years, Gonstead helped the company define the device's sensitivity, parameters, and function.

[9][10][11] Gonstead's first office was located above a bank building in downtown Mount Horeb, Wisconsin.

[12] The next year, 1965, a motel (Karakahl Country Inn) was constructed next to the clinic to accommodate out-of-town patients and chiropractors attending his seminar.
