Larry Tesler, a pioneer in early computing, has died at the age of 74.
The death of Larry Tesler was announced on Twitter on Wednesday by Xerox, where he worked.
Tesler spent 17 years at Apple, rising to chief scientist.
“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,” Xerox paid tribute to him.
Tesler, an American computer scientist who worked in the field of human–computer interaction spent his career at Xerox PARC, Apple, Amazon, and Yahoo.
Silicon Valley’s Computer History Museum said Mr Tesler “combined computer science training with a counterculture vision that computers should be for everyone”.
While at PARC, Tesler developed the idea of copy and paste functionality and the idea of modeless software.
Tesler’s most famous innovation, the cut and paste command, was reportedly based on the old method of editing in which people would physically cut portions of printed text and glue them elsewhere, BBC reports.
Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California.
