There was a time when people had to type every single word from the sources they’re researching from until the day Mr. Tesler, from Silicon Valley, creates a revolutionary function that we still use in all our devices today: the copy, cut, paste option.

Xerox (XRX), the company for whom he developed the functions, tweeted out news of his death. “Your workday is easier thanks to his revolutionary ideas,” the company’s tweet said.
The inventor of cut/copy & paste, find & replace, and more was former Xerox researcher Larry Tesler. Your workday is easier thanks to his revolutionary ideas. Larry passed away Monday, so please join us in celebrating him.

Tesler served as a consultant for a company called Western Union until his death at the age of 74. His projects always championed simplification, innovation, and availability.
