Larry Tesler, inventor of the cut, copy, and paste commands, dies at 74.


Tesler was chief scientist at Apple in the ’90s, and contributed heavily to the field of human-computer interaction.

Computer scientist Larry Tesler, who was an instrumental figure at Apple in the ’80s and ’90s, died on Monday at the age of 74, according to Apple Insider.

Tesler began his career in the ’60s as a programmer and Stanford AI researcher before joining Xerox in 1973.

One of his inventions during his time at Xerox is something so ubiquitous, it’s easy to forget that someone invented it.

With Tim Mott at Xerox, Tesler created the cut, copy, and paste commands we use daily.

He didn’t invent the fundamental idea of moving digital text from one place to another, but did create the specific method and naming convention that endured.
