Who invented the walkie talkie?

The first radio receiver/transmitter to be nicknamed "Walkie-Talkie" was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (forerunner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Bill Vogel, Lloyd Morris, and Marion Bond. Motorola produced the hand-held AM SCR-536 radio as well during the war. It was called the "Handie-Talkie" (HT).

Al Gross is sometimes said to have invented it. He also worked on the early technology behind the device from 1934 to 1941.
