téléphone Design 70
The Ericofon was designed in the late 1940s by a design team including Gösta Thames, Ralph Lysell, and Hugo Blomberg.[3] The two major components of the telephone, the handset and the dial, are combined in a single unit. This one-piece design anticipated the evolution of the typical cordless phone and cell phone by several decades. Serial production began in 1954. Early models were sold only to institutions, but in 1956 production for the open market began in Europe and Australia.
As the Bell System did not permit the operation of third-party equipment on their network, the Ericofon could only be used by independent telephone companies in the United States. North Electric in Galion, Ohio, manufactured the Ericofon for the North American independent market.
