Thirteen years ago the Wham-O Manufacturing Company of San Gabriel, Calif., ... brought out the first Frisbee. Wham-O purchased the rights from a Los Angeles building inspector named Fred Morrison, who in turn had been inspired by the airworthy pie tins of the Frisbie Bakery in Bridgeport, Conn. (which went out of business in March of 1958). He changed the spelling to avoid legal problems. [Sports Illustrated, Aug. 3, 1970]
