Who invented cellphones?

The idea of cellphones is not new to the human race. Its development started in the year 1947 when these were used mainly for military operations and required a large backpack device to transmit phone’s signals to the nearby power stations. It was Doctor Martin Cooper who invented the first cellphone on April 3,1973. During this tenure he was working as the Director of Development and Research at Motorola. The phone was named Motorola Dyna-Tac, it weighed 2.5 pounds and had a talktime of 35 minutes.  It was first used in the U.S.A. and the first call was made by Cooper to Joel Engel, his rival, who was working as the head of research at Bell Labs. Cooper was brought up in Chicago. He got his degree in Electrical Engineering from Lllinois Institute Of Technology.  He served the Navy for four years and in 1954 he joined Motorola and started working on portable products. He is now working as the CEO and founder of Arraycomm.
