AutoDesk

Autodesk makes Auto C A D software.

John Walker was founder, and creator of the Autodesk File: http://www.fourmilab.ch/autofile/www/autofile.html

For a while Autodesk got really futuristic in its investments: AMIX, Xanadu, chaos software with Rudy Rucker, etc. But then the core business started to slide, and they dumped that stuff in 1992.
