Who made the mobile phone? History

The invention of the mobile phone was not the work of a single person but a process of gradual development. However, the first handheld mobile phone (the kind we think of today) was developed by Martin Cooper and his team at Motorola. In 1973, Martin Cooper made the first public mobile phone call using a prototype called the Motorola DynaTAC. Earlier forms of mobile communication (car phones, radio phones) existed in the 1940s–60s, but they were large and limited. So, while many scientists contributed to wireless communication, Martin Cooper is widely credited as the “father of the cell phone” because of his role in creating the first practical handheld mobile phone.
