Steven P. Jobs, may he rest in peace.
Stephen Wolfram reflects on Steve Jobs' influence on the development of Mathematica, including the name. Mathematica was bundled on all NeXT computers at the debut, apparently. And this interesting aside:
And as a curious footnote to history (which I learned years later), one batch of NeXTs bought for the purpose of running Mathematica went to CERN in Geneva, Switzerland—where they ended up having no less distinction than being the computers on which the web was first developed.
You can still download some of the early code from 1991-ish by Tim Berners Lee, the first "WorldWideWeb" browser written in Objective-C.
