An American computer scientist who invented the widely used computer concept, ‘cut-copy-paste’, Larry Tesler, has died at age 74.

The concepts became instrumental to user interface building blocks for both text editors and entire computer operating systems.

The news of Mr Tesler’s death was divulged to the world in a tweet by Xerox, a U.S. tech company where he worked with before his death.

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

The company said he died on Monday without giving any information about where he had died or the cause of his death.

“Your workday is easier thanks to his revolutionary ideas. Larry passed away Monday, so please join us in celebrating him,” the company said.

A graduate of Stanford University, Mr Tesler specialised in human-computer interaction, employing his skills at Amazon, Apple, Yahoo, and the Xerox Palo Alto Research Center (PARC).
