“This preposterous quackery flourishes lushIy in the back reaches of the Republic, and begins to conquer the less civilized folk of the big cities. As the old-time family doctor dies out in the country towns, with no competent successor willing to take over his dismal business, he is followed by some hearty blacksmith or ice-wagon driver, turned into a chiropractor in six months, often by correspondence. In Los Angeles the Damned, there are probably more chiropractors than actual physicians, and they are far more generally esteemed. Proceeding from the Ambassador Hotel to the heart of the town, along Wilshire boulevard, one passes scores of their gaudy signs; there are even chiropractic “hospitals.” The Mormons who pour in from the prairies and deserts, most of them ailing, patronize these “hospitals” copiously, and give to the chiropractic pathology the same high respect that they accord to the theology of the town sorcerers. That pathology is grounded upon the doctrine that all human ills are caused by pressure of misplaced vertebrae upon the nerves which come out of the spinal cord — in other words, that every disease is the result of a pinch. This, plainly enough, is buncombe. The chiropractic therapeutics rest upon the doctrine that the way to get rid of such pinches is to climb upon a table and submit to a heroic pummeling by a retired piano-mover. This, obviously, is buncombe doubly damned.”

That’s just the opening paragraph from a 1924 essay in the Baltimore Sun.
