Larry Tesler: The Man Behind Cut, Copy, and Paste Passes Away

Larry Tesler, the inventor of copy-paste, transformed user interfaces and made computers accessible to everyone passes away.

Larry Tesler: The Man Behind Cut, Copy, and Paste Passes Away

Larry Tesler was a pioneering computer scientist whose innovations transformed human-computer interaction. Best known for developing the ubiquitous "cut, copy, and paste" commands, Tesler's work laid the foundation for modern user interfaces and made computing more accessible to the masses.

Larry Tesler's Early Life and Education

Larry Tesler was born on April 24, 1945, in the Bronx, New York City. He graduated from the Bronx High School of Science in 1961 and went on to study computer science at Stanford University, earning his degree in 1965. 

During his time at Stanford, Tesler became involved in the counterculture movement, participating in anti-Vietnam War protests and teaching classes on topics like "How to End the IBM Monopoly" and "Computers Now".

His Career at Xerox PARC

In the late 1960s, Tesler joined the Stanford Artificial Intelligence Laboratory (SAIL), where he worked on the development of early programming languages and systems. 

He later moved to Xerox's Palo Alto Research Center (PARC), where he became a key figure in the development of graphical user interfaces (GUIs).

At PARC, Tesler co-developed the Gypsy word processor, one of the first to feature a GUI, and worked on Smalltalk, an early object-oriented programming language.

Larry Tesler's Contributions to Apple

In 1980, Tesler joined Apple Inc., where he played a pivotal role in the development of the Apple Lisa and Macintosh computers

He is credited with introducing the "cut, copy, and paste" commands to Apple's software, making text editing more intuitive and user-friendly. These commands were incorporated into the Lisa computer in 1983 and the original Macintosh the following year.

Tesler also contributed to the development of other significant Apple technologies, including QuickTime, AppleScript, and MacApp. He served as Apple's Chief Scientist until 1997.

Later Career and Legacy

After leaving Apple, Tesler co-founded Stagecast Software, an educational technology company, and later worked at Amazon and Yahoo! in various roles related to user experience and design. 

He also served as a consultant, helping companies improve their user interfaces and user experiences

Tesler's commitment to user-friendly design was evident in his strong preference for "modeless" software, where user input has a consistent effect without the need to switch between different modes.

He even equipped his car with a personalized California license plate reading "NOMODES" to promote this principle.

Larry Tesler passed away on February 16, 2020, at the age of 74. His contributions to computing continue to impact the way we interact with technology today.

Larry Tesler's innovations have left an indelible mark on the field of computer science. His work on the "cut, copy, and paste" commands revolutionized text editing and made computers more accessible to users. 

Through his dedication to user-friendly design and his belief that "computers should be for everyone," Tesler helped shape the modern computing experience.
