Larry Tesler, a computer scientist who is most well-known for creating the seminal computer concepts cut, copy and paste, died on Monday at age 74.
Mr Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California.
Mr Tesler started working in Silicon Valley in the early 1960s, at a time when computers were inaccessible to the vast majority of people.
It was thanks to his innovations – which included the “cut”, “copy” and “paste” commands – that the personal computer became simple to learn and use.
Tesler was also a champion of a concept called “modeless” computing, which is the idea that a program shouldn’t have different “modes” where a user’s input does different things based on whichever mode you’re in.
