Q: What does a fax machine, an electric organ and the NBC chimes all have in common?
A: Richard Howland RangerBorn in Indianapolis, IN in 1889, Richard Ranger would become a strangely successful engineer. He served in the U.S. Army Signal Corps during World War I, and attended the Massachusetts Institute of Technology (MIT) from 1919 to 1923. (It does not appear he actually graduated.)
After leaving MIT, Ranger became an engineer at RCA in 1924. There he conceived his first major accomplishment: the photo-radiogram aka radio fax. It was also called the transoceanic radio facsimile. In 1924 he sent a photograph of President Calvin Coolidge from New York to London as a demonstration.There were other systems: the Denison facsimile as early as 1901, the Korn system in 1922, the Jenkins process and Bart-Lane systems were also around by 1922, the Belin and Feree Systems by 1924. But RCA system developed by Ranger is the one today's fax is descended from.
In 1930 he left RCA and founded his own company, Rangertone Inc, in Newark, NJ. His company manufactured and sold his electronic organ the "Rangertone." It wasn't the first electric organ, other less elegant devices predated the Rangertone by decades. It was a electronic tone-wheel based organ. Related tone-wheel organs go back to at least 1897 and the Telharmonium. In truth Rangertone didn't made big money until the late 1940s when they got into audiophile equipment. More here.
