Bartlett Joshua Palmer

Bartlett Joshua (B.J.) Palmer (September 14, 1882 – May 21, 1961), born in What Cheer, Iowa, was the son of Daniel David Palmer (D.D.), the founder of chiropractic, and became known as the "Developer" of chiropractic.

B.J. Palmer was born on September 14, 1882, the son of Daniel David Palmer (or "D.D."), the founder of chiropractic. The Palmer family of six resided in the back of a grocery store that D.D. operated. In 1885 D.D.'s wife became sick and died, after which D.D. remarried several times. When D.D. had settled with a new wife, he moved the family to Letts, Iowa, and he worked as a schoolteacher and a magnetic healer, developing chiropractic.

When D.D. had developed chiropractic, he felt the desire to keep it secret for fear of others stealing his ideas. Following a near-fatal train accident that D.D. was involved in, B.J. convinced his father, D.D., to teach chiropractic to others so that it would not be lost. D.D. was reluctant to allow B.J. to learn chiropractic, but eventually gave in and allowed B.J. to study under him. B.J. assumed control of the school that his father had founded in Davenport, Iowa. As a result of his development and promotion of the profession, B.J. became known as the "Developer" of chiropractic.

On May 30, 1904, B.J. married a woman named Mabel Heath. Both worked as chiropractors and instructors at Palmer College. Mabel Heath Palmer had a heavy load of students and taught mostly anatomy classes. B.J. Palmer ran his research clinics in Davenport for 16 years and eventually became convinced that upper cervical spine was the key to health. He coined the new method "Hole-In-One" (HIO) as known as Upper Cervical via Toggle Recoil application.Subsequently, he modified the PSC (Palmer School of Chiropractic) curriculum to reflect his new ideas. Palmer advocated the use of the Neurocalometer and X-ray machines.

On January 12, 1906, a son David Daniel Palmer was born to B.J. and Mabel Heath, and would be the couple's only child. In keeping with his educational efforts for the profession, he became known as "The Educator." They had an estranged relationship for a number of years when David Daniel decided to attend University of Pennsylvania and later its Wharton School of Business. David explained that he knew that he would one day be in charge of the school, and wanted an education in business to allow him to better manage the college. He also graduated from Palmer as a Doctor of Chiropractic.
