X-Ray Opera Glasses

I'm reading (well, really, listening to) this great book, and in it there was an account of how, around the time that xrays were first introduced and first being used, the new technology caused quite a stir. "News of the x-ray caused a public fervor, raising a fascination with (and fresh fears of) technology. In London, a firm began selling x-ray-proof underwear. New York State tried to pass legislation banning the possibility of using x-rays in opera glasses.(Karolevitz RF, Doctors of the Old West)".

I also learned about the wacky life-goal of Duncan MacDougall.
