Ralph Vinton Lyon Hartley (November 30, 1888 – May 1, 1970) was an American electronics researcher. He invented the Hartley oscillator and the Hartley transform, and contributed to the foundations of information theory.
His legacy includes the naming of the hartley, a unit of information equal to one decimal digit, after him.
