Larry Tesler, Computer Scientist Who Created Cut, Copy, and Paste, Dies At 74

Larry Tesler, a computer scientist who created the terms "cut," "copy," and "paste," has passed away at the age of 74. Gizmodo reports: Born in 1945 in New York, Tesler went on to study computer science at Stanford University, and after graduation he dabbled in artificial intelligence research (long before it became a deeply concerning tool) and became involved in the anti-war and anti-corporate monopoly movements, with companies like IBM as one of his deserving targets. In 1973 Tesler took a job at the Xerox Palo Alto Research Center (PARC) where he worked until 1980. Xerox PARC is famously known for developing the mouse-driven graphical user interface we now all take for granted, and during his time at the lab Tesler worked with Tim Mott to create a word processor called Gypsy that is best known for coining the terms "cut," "copy," and "paste" when it comes to commands for removing, duplicating, or repositioning chunks of text.

Xerox PARC is also well known for not capitalizing on the groundbreaking research it did in terms of personal computing, so in 1980 Tesler transitioned to Apple Computer where he worked until 1997. Over the years he held countless positions at the company including Vice President of AppleNet (Apple's in-house local area networking system that was eventually canceled), and even served as Apple's Chief Scientist, a position that at one time was held by Steve Wozniak, before eventually leaving the company.

In addition to his contributions to some of Apple's most famous hardware, Tesler was also known for his efforts to make software and user interfaces more accessible. In addition to the now ubiquitous "cut," "copy," and "paste" terminologies, Tesler was also an advocate for an approach to UI design known as modeless computing, which is reflected in his personal website. In essence, it ensures that user actions remain consistent throughout an operating system's various functions and apps. When they've opened a word processor, for instance, users now just automatically assume that hitting any of the alphanumeric keys on their keyboard will result in that character showing up on-screen at the cursor's insertion point. But there was a time when word processors could be switched between multiple modes where typing on the keyboard would either add characters to a document or alternately allow functional commands to be entered.
