Computer scientist ,cut, copy and paste
In the early 1960s Mr Tesler started working in Silicon Valley, at a time when computers were inaccessible to the vast majority of people.
It was due to its inventions – which included the commands "cut," "copy" and "paste" – that the personal computer was easy to understand and use.
Xerox, where Mr Tesler has spent most of his career, paid him homage.
"Former Xerox researcher Larry Tesler was the inventor of cut / copy & paste, scan & replace, and more," the company tweete. "Thanks to his innovative theories, the workday is simpler." Mr. Tesler was born in 1945 in the Bronx, New York, and studied in California at Stanford University.
He specialized in user interface design after graduation-that is, making computer systems more user-friendly. During his long career he has worked
for a variety of big tech firms.He started at the Xerox Palo Alto Research Center (Parc) until he was poached for Apple by Steve Jobs, where he spent 17 years, and rose to be the chief scientist. He set up an educational startup after leaving Apple, and worked at Amazon and Yahoo for brief periods. He told Silicon Valley's BBC in 2012: "There is almost a rite of passage – once you've made some money, you're not just retiring, you're spending your time helping other companies."There is a very strong dimension of curiosity, of being able to share with the next generation what you have learnt."
‘A counterculture vision’
Perhaps the most popular invention of Mr Tesler, the cut-and-paste order, was allegedly based on the old editing system in which people would physically cut parts of written text and add it elsewhere. The command was implemented on the Lisa computer in Apple's program in 1983, and the first Macintosh was released the next year. One of Mr Tesler's firmest convictions was that computer systems would avoid using "modes," which at the time was popular in software design.
Modes allow users to switch between program and device features, thus making computers both time-consuming and complicated.
This belief that the website of Mr Tesler was named "nomodes.com" was so powerful,Probably the most popular invention of Mr Tesler, the cut and paste order, was based on the old editing system in which the Silicon Valley Computer History Museum said Mr Tesler 'combined computer science training with a vision of counterculture that computers should be for all.'
