The mobile phone exists thanks to the work of a Scottish scientist in the 1800s, according to an academic.

As the 40th anniversary of the first mobile phone call is celebrated, a professor at the University of Edinburgh claims it would never have happened without an Edinburgh physicist.

In 1865, James Clerk Maxwell discovered the laws of electromagnetic radiation.

It enabled scientists to understand how electromagnetic fields could be used to transmit signals and led to the development of wireless communications such as the telegraph and radar.

Professor Peter Grant is giving a talk at the Edinburgh International Science Festival on Sunday where he will claim mobile phones would not exist without Maxwell’s research.

Professor Grant said: "The mobile phone market today is worth more than a trillion dollars annually. It's interesting to consider the events and personalities that helped to shape the devices that we all rely on every day."

His talk looks at the growth of smartphones and tablets and how they are changing the way we communicate.
