The Billings Clinic was founded by Dr. Arthur J. Movius, who started his Billings medical practice in 1911. In 1915, after practicing on his own, Movius had Dr. J.H. Bridenbaugh join him as an assistant. Bridenbaugh operated and managed obstetrics and began working with a ground-breaking device, the x-ray machine. During World War I, Bridenbaugh joined the military, where he received training in radiology. After returning from the war, Bridenbaugh incorporated diagnostic x-rays and radiation therapy into his practice.
