In the century since founder D.D. Palmer made his "First Adjustment" in 1895, chiropractic has grown to become the second largest healing group in America (after medical doctors) and the most widespread drugless therapy in the world. Now, in Chiropractic in America, J. Stuart Moore has written the first book to place this unorthodox medical movement in its proper historical setting, examining its relation to other sects, to religious beliefs, and to orthodox medicine. Moore offers new interpretations of chiropractic's central schisms - disagreements between so-called "straights" and "mixers", as well as conflicts between D.D. Palmer and his son B.J. - and of the effects of nineteenth-century professionalization on the fledgling movement. Drawing on previously unpublished archival material, he also examines colorful claims by inventors of such devices as the "Polysine Generator" and the "Semiautomatic White Light Instrument".
