Walkie-talkie - the Motorola's iconic invention was created by a Pole. Engineer Henryk Manguski was a key member of the Motorola's team that developed the device. In early 1943, Motorola has provided the US Army with SCR-300 radio station with FM modulation. The soldiers called the device simply walkie-talkie. After the war, the walkie-talkies were more widely used. Three patents used in the first model of the device are attributed to the inventor of the Polish origin. Manguski was born in Warsaw in 1909. In 1939 he was sent on business to New York to study the American radio transmitters. The outbreak of World War II prevented his return to Poland.
