A hundred years ago, X-rays were supposed to be good for all sorts of things. Now we know better. In The X-ray Century, Perry Sprawls and Jack E. Petersen reproduce a series of reports on the discoveries of Roentgen and others in 1896 (start with the last page and work backwards). They include a summary of Edward Trevert’s Something about X-rays for Everybody, published in 1896.
Trevert’s full name was Edward Trevert Bubier. He wrote popular books on electricity and radio, including the Electro-therapeutic handbook, with full directions for home treatment of nearly all diseases that can be cured or relieved by the application of electricity (New York: Manhattan Electrical Supply Co., 1900) and The ABC of wireless telegraphy, a plain treatise on Hertzian wave signalling (Lynn, Mass.: Bubier Publishing, 1906).
Something about X-rays has been reprinted in facsimile (Medical Physics Publishing, 1988).
