Douglas H. Ring (March 28, 1907 in Montana – September 8, 2000 in Red Bank, New Jersey) was one of the Bell Labs engineers that invented the cell phone. The history of cellular phone technology began on December 11, 1947 with an internal memo written by Douglas H. Ring in which he proposed development of a cellular telephone system by AT&T.
Although Martin Cooper of Motorola is considered the inventor of the first handheld cellular telephone and the first person to demonstrate to reporters a handheld cell phone call, Cooper's April 1973 call used cellular telephone technology invented and developed by Bell Labs engineers.
