Powell Crosley is considered by many to be the "Henry Ford" of early radio. After watching his children playing with crystal radios he decided to look into radios. He already had manufacturing capabilities in his businesses, so he bought Precision Mfg. (Ace radios) to acquire the Armstrong patent rights to produce radios. The Crosley 50, 51 and 52 were some of his first radios. His company still exists today.
