The idea of the cell phone began in the 1920's with police radios, but it wasn't until 1947 that the first one was made by Bell labs. In 1974 Dr. Martin Cooper is given credit for the cell phone that is most like the ones we have today. He was working for Motorola at the time. The phone was only for government use and in 1984 it was sold to the public for the first time. The early cell phones were large, heavy, and copied land line phones in style. They were carried in a zippered bag with the whole bottom as the battery. The cell phone was first thought of in the 1920's when the use of police radios began.

What did they use before cell phones were invented?
Believe it or not, there was once a time when if someone wasn't at home, there was literally NO WAY to communicate with them without going out and looking for them. And even more amazingly, people somehow managed to live like that. Actually, there were "mobile phones" before cell phones existed. They were large and heavy and ridiculously expensive both to buy and to use, but for people who absolutely had to be reachable at all times for business reasons, they did exist (they were usually semi-permanently installed in vehicles). There were also pay phones, and if you didn't mind other people listening in, you could use a citizen's band radio (kind of like walkie-talkies, but with more channels) and hope the person you wanted to reach was listening.
Who is the father of electronics and communication?
There is no "father". It is a cumulative effort of many people. The transistor has advanced electronics as much as anything else has but that also was a cumulative effort at Bell Labs. Without the original pioneers, we would still be discovering the rules, but they would have been discovered. We build upon our predecessors' knowledge base. Bill Gates didn't invent the computer but he helped advance the technology as did Steve Jobs and Steve Wozniak,
