Larry Tesler, an icon of early computing, has died at the age of 74. Mr Tesler has given a huge contribution in the sector of computer science. He 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.

Mr Tesler was born in the Bronx, New York, in 1945, and studied at Stanford University in California.
