The handheld mobile phone is most widely credited to engineer Martin Cooper of Motorola, who led the team that built the first portable cell phone and made the first public mobile call in 1973.

Quick Scoop

  • Martin Cooper (Motorola engineer) is often called the father of the handheld cell phone.
  • On April 3, 1973, he made the first public call from a handheld mobile phone on a New York City street, using a prototype later known as the DynaTAC.
  • Earlier “mobile phones” in cars and radio-telephone systems existed before this, but they were bulky, limited, and are usually seen as precursors, not true handheld mobiles.

Who “invented” the mobile phone?

  • Cooper led a Motorola team in 1972–73 that developed the first practical handheld cellular phone, the DynaTAC, which weighed about 1.1 kg and allowed roughly 30–35 minutes of talk time.
  • Because he directed the project and made the first public call, history and media generally credit him as the inventor of the handheld mobile phone, even though it was a large team effort.

But it wasn’t just one person

  • Bell Labs engineers had earlier proposed the “cell” concept for mobile networks in 1947, laying the groundwork for cellular systems long before Cooper’s call.
  • Various companies had car phones and radio-telephone services from the 1940s onward, so some historians emphasize a chain of innovations rather than a single inventor.

From prototype to first commercial phone

  • The famous DynaTAC 8000x, the first commercially available handheld cell phone, was approved by the U.S. FCC in 1983 and then sold to consumers at a very high price.
  • This early phone, sometimes nicknamed a “brick,” marked the shift from experimental mobile tech to a mass-market product, starting the mobile revolution that led to today’s smartphones.
