D. D. Palmer

Daniel David Palmer (March 7, 1845 - October 20, 1913) was a Canadian-born magnetic healer and the founder of Chiropractic, a school teaching that spinal adjustment, correcting subluxated vertebra, can cure physical ailments.

In his 1910 book The Chiropractor's Adjuster, Palmer stated that he received information on chiropractic from a Dr. Jim Atkinson, the spirit of a then fifty-years deceased physician. This has been argued by modern researchers to have been an intentionally fraudulent claim intended to bolster the religious credentials of chiropractic to evade any potential crackdown by medical authorities, following the model of Mary Baker Eddy and Christian Science.
