When radio broadcasting began in the early 1920s, the radio was a magic box aglow with the future, drawing humanity into a new age. Some thought it would dissolve the distance between time and place, others that human minds would become transparent, one tuned to another. Performers claiming psychic powers turned radio broadcasting into a fabulous money machine. These mentalists, born from vaudeville, circuses, sideshows, and the Spiritualist and New Thought movements of the mid-late 19th century, used the language of wireless technology to explain their ability to see the past, present, and future. Casting their mystical knowledge as a scientifically honed craft, these mentalists persuaded millions to pay for dubious advice until governmental and public pressures forced them off the air.

This book is a history of over 25 performers who practiced their art behind studio microphones during the early years of radio broadcasting, from about 1920 to 1940. Here, laid out for the first time, is the tale of how they made cash rain from the heavens and harnessed the sensation of the radio in search of wealth, health, love, and success.
