Norman G. Baker (November 27, 1882 – September 10, 1958) was an early American radio broadcaster, entrepreneur and inventor who secured fame as well as state and federal prison terms by promoting a supposed cure for cancer in the 1930s. He operated radio stations KTNT in Muscatine, Iowa and the border blaster XENT in Nuevo Laredo, Tamaulipas. Baker was also the creator of the Tangley calliaphone (an air blown musical instrument similar to a calliope).
