"father of Windows"
DW,
A minor point - Windows appeared on the original Apple Mac well before Bill G. was involved. IIRC it was on the Apple Lisa before that.
I'm told the mouse part of the WIMPs interface (Windows, Icons, Menus and Pointing devices) was a spin-off from a Xerox trackball used in missile guidance well before the Mac.
I mention this only because MS and IBM are often given the credit for the PC. They were well behind.
