His invention helped millions of users .. Death misses the creator's cut and paste feature

The famous American computer scientist and science computing technologist Larry Tessler, 74, has died, and he has developed many computer features that have made millions easier to work with texts written on those devices.

Tesler graduated in 1965 from Stanford University with a degree in computer science, and later specialized in designing the user interfaces for these devices.

In 1973, he joined the Xerox PARC Research Center and contributed to the development of a number of computer-specific features, including "cropping", "copying" and "pasting" that made it easier for millions to deal with texts written in those devices, and also contributed to the development of Computer mouse technologies.

In 1980, Tesler began working with Apple, and he contributed to the development of many products, such as MessagePad and Lisa, to leave in 1997.

He then worked for Stagecast, an emerging education company that was affiliated with Apple, and collaborated with some well-known companies such as Yahoo and Amazon.
