D.D. Palmer: the origins of the Palmer School and the itinerant schoolman, 1897-1913.

Gibbons RW.

For the last sixteen years of his life, Daniel David Palmer was involved in at least ten institutions in four states offering a course in chiropractic. In a five year period spanning the end of nineteenth and the start of the twentieth centuries, D.D. began the chiropractic educational experience with the Chiropractic School and Cure in Davenport's Ryan Building, suceeded by the Palmer School and Infirmary of Chiropractic (PSIC), followed by the Palmer School of Chiropractic. Further documentation is needed to place Palmer in the East during late 1900, where he may have engaged in the first of his preceptor schools. The Discoverer went to California in 1902 where he presided over the Chiropractic School and Infirmary first in Pasadena and then in Santa Barbara. Returning to Davenport, he joined his son B.J. at the school until he sold his interest in 1906 and moved to Oklahoma City. Between 1907 and 1908, he was part of the Palmer-Gregory College and then his own Palmer College, moving to Portland, Oregon. This involved two institutions through 1911, when the senior Palmer settled in Los Angeles, conducted his own school and lectured at the Ratledge and Universal colleges until his death.
