James F. McGinnis, D.C., N.D., C.P. (1873-1947): spinographer, educator, marketer and bloodless surgeon

Perhaps best remembered for his contributions to B.J. Palmer's earliest developments in spinography, James F. McGinnis also pioneered in marketing methods while a straight chiropractic practitioner in Iowa. His advertising brought him to the attention of organized medicine, which sought his prosecution. Relocating to California in the early 1920s, he broadened his scope of practice and earned a naturopathic doctorate. In the 1930s he became one of the best known of several chiropractic bloodless surgeons and traveled around the nation to teach his methods. Although initially a passionate member of the Universal Chiropractors Association and receptive to Palmer's introduction of the neurocalometer, McGinnis eventually changed his political allegiance and became an active member of the National Chiropractic Association. He died in 1947 while on a teaching tour of Claifornia's San Joaquin Valley.
