who made the first mobile phone in the world
History of mobile phones Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles.[20] Motorola was the first company to produce a handheld mobile phone. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs, his rival.[26][27] The prototype handheld phone used by Dr. Cooper weighed 1.1 kg (2.42 lb) and measured 23 cm long, 13 cm deep and 4.45 cm wide. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.[28]
Martin Cooper (inventor) While at Motorola in the 1970s, Cooper invented the first handheld cellular mobile phone (distinct from the car phone) in 1973 and led the team that developed it and brought it to market in 1983.[3][4] He is considered the "father of the (handheld) cell phone"[1][3][5][6] and is also cited as the first person in history to make a handheld cellular phone call in public.[7]
