Teletype Impact

"This typeface, which Young designed for the Teletype machine, originated with Henry Dreyfuss and Associates—the industrial design office in South Pasadena renowned for such legendary American products as the standard black dial telephone, the Big Ben alarm clock, and various models of the John Deere tractor and Polaroid camera. Teletype was an early digital means of transmitting text via telephone lines, allowing a message typed into the system at one end to be received as typed output at the other." –Louise Sandhaus, Earthquakes, Mudslides, Fires & Riots: California and Graphic Design 1936-1986, pp. 96-97
