Dr. Martin Cooper - Cell Phone

Dr. Martin Cooper made the first phone call on a cell phone in April 1973. Who did he call? He called one of his rivals, Joe Engel, who was the head of research for Bell Laboratories. Both men had been working on inventing a portable cell phone. The technology for cell phones had been available since 1947, but the Federal Communications Commission severely limited the amount of radio frequencies available for cellular service. Without the availability of enough radio frequencies to provide adequate service, the companies had no incentive to further research cell phone possibilities. In 1968, the FCC reconsidered and promised it would make ample radio frequencies available, if a working cell phone was invented and made available to the public consumer.

Dr. Cooper received his bachelor's degree in electrical engineering from the Illinois Institute of Technology in 1950. He then served in the Navy for four years, before joining Motorola Corporation, as a researcher in 1954. While working at Motorola, Cooper attended night school, again at Illinois Institute of Technology, to earn his master's degree. The first portable communication product Cooper worked on, while at Motorola was a hand held radio that he designed for the Chicago police department. Cooper envisioned creating a phone that would allow people to communicate with one another, regardless of where they were and were the person was they were calling. He set out to invent a phone that would "untether" people from the telephone.

Based on his prior research in portable, radio driven communication devices, over a three month period in 1973, Dr. Martin Cooper invented the first cell phone. The phone weighed approximately two pounds and operated on 800 MHz. Cooper tested the phone for the Federal Communications Commission in Washington D.C. Then he traveled to New York to for a public demonstration for the press. In April of 1973, Cooper called his rival, Dr. Joel Engel, who was the headed of research at Bell Labs. Dr. Engel was also working on inventing a cellular telephone, but had not yet produced a working model. Dr. Cooper filed for a patent in October 1973.

Martin Cooper continued to work in the cellular industry. He started and sold several companies that provided services to cellphone service providers.
