Larry Tesler, an icon of early computing, has died at the age of 74.

Mr Tesler started working in Silicon Valley in the early 1960s, at a time when computers were inaccessible to the vast majority of people.

It was thanks to his innovations – which included the “cut”, “copy” and “paste” commands – that the personal computer became simple to learn and use.

Xerox, where Mr Tesler spent part of his career, paid tribute to him.

“The inventor of cut/copy & paste, find & replace, and more, was former Xerox researcher Larry Tesler,” the company tweeted. “Your workday is easier thanks to his revolutionary ideas.”

Mr Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California.
