You use things he worked on everyday, one of them is UTF-8. He also designed and implemented UNIX. He was creator of B language, thanks to which we have C language. He also worked on Golang and Plan9.

And even wider, almost everything in the modern world was invented at Bell Labs.

Or Xerox PARC.

Sorry downvoter but you really have no idea how much more Bell-Labs has done.

The Simplex algorithm, the transistor, C and C++, the R programming language, the ccd, the mobile phone...

Just some from the top of my head

No need to be dismissive. This isn't a peeing contest.

OOP, Ethernet, the mouse, GUIs, and tablets were some of the things invented at Xerox PARC.

But I am dismissive. Xerox Parc, as influential as it's been is still merely drops in the ocean compared to the Labs.

That was Ken Olsen
