Larry Tesler was a great figure in computing history, but why is this being reposted now? "Inventor of Cut/Paste" is such a ... limited ... way to describe his accomplishments.
Limited, and also wrong -- Tesler didn't invent any of those. They existed already by 1973 (supposed date of these inventions at Xerox PARC); e.g. TECO from MIT and E from Yale had functionality for cutting/pasting, replacing strings, etc.
> In 1969 Tesler volunteered to help create a catalog for the Bay Area’s Mid-Peninsula Free University. He and Jim Warren, founder of the West Coast Computer Faire, did the paste-up for that catalog. Around the same time, Tesler saw a demo of a computer command that allowed you to bring back something that you had deleted. The command was called “Escape P Semicolon” (or something similarly arcane). Several years later, when Tesler was at Xerox PARC writing a white paper about the future of computing, he drew on the memory of those two experiences to predict that you would be able to “cut and paste” within computer documents.
