Daily Image – Original Mobile Phone
Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles. Motorola and Bell Labs raced to be the first to produce a handheld mobile phone. That race ended on April 3, 1973 when 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. The prototype handheld phone used by Dr. Cooper weighed 2.5 pounds and measured 9 inches long, 5 inches deep and 1.75 inches wide. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.
