Washington, D.C: Larry Tesler, the computer pioneer who developed the ingenious cut, copy and paste functions, passed away on Monday (local time) at the age of 74. These widespread computer functions, which we often take for granted, have made the lives of countless computer users easier for many years to come, and will continue to do so for the foreseeable future.

The Verge quoted Gizmodo as saying that Tesler, born in New York in 1945, graduated in computer science from Stanford University. It was 1973 when he developed the cut, copy and paste functions while working at Xerox's Palo Alto Research Center (PARC).

PARC is well known for its first research into the graphical user interface and its use with a computer mouse. According to The Verge, Tesler was also an advocate of "modelless" computing, a concept that ensures that a computer application should not have separate "modes" in which user input, depending on the mode in which the application is run, leads to different expenses.

Tesler also worked at Apple for a long time between 1980 and 1997, where he contributed to the development of numerous products such as Macintosh, QuickTime, Lisa and the Newton tablet.

Lisa and Macintosh were the first PC platforms to introduce the cut, copy and paste functions that were made possible primarily through Tesler's involvement.

In 1993, Tesler was promoted to chief scientist, a role that Steve Wozniak also held, quoted The Verge Gizmodo.

Then Tesler switched to Stagecast, a startup for educational software that had emerged from Apple.

After working for information technology giants such as Amazon and Yahoo from 2009, he founded a UX consulting firm in California.
