46 years ago today, the first ever phone call was made on a mobile phone by Martin Cooper and delivered to Joel S. Engel. Cooper used a handheld mobile phone to make the call. When he made the call, Cooper was present at an interview with reporters at a 900-MHz base station when he sent the call to the Headquarters of Bell Labs. Cooper believed that a cell phone is “something that would represent an individual so you could assign a number – not to a place, not to a desk, not to a home – but to a person.” After Cooper made the call, people thought it to be a “major step in the development of mobile technology.”
