It had three parents: OS/2, DOS and VMS. However, MS could use code from 2 of them but not from VMS. I've blogged about this more than once:

Nope. Not true, and you have the timeline backwards.
NT was released in 1993, 2 years before Win95, and only the 2nd version of NT, 3.5, supported VFAT long file names.
NT did not support Win95B's FAT32 until its 5th release, Windows 2000.
> backward compatibility reasons, but I bet everybody on the NT team hated those requirements
No, I don't think so. NT could be installed on top of DOS, via the WINNT.EXE setup program. (Something I urged in OS/2 communities, but they didn't understand the need or usefulness.)

NT could dual-boot with DOS, even in the same partition in early versions. It could also dual-boot with Win9x.
This level of interop was hugely important and useful and really helped the new OS gain adoption. It was not some reluctant bolt-on.

No, it isn't. It's a horrid calumny against a good and brilliant man.
> not much different from "Gary Kildall was not interested".
Also utter nonsense.

TL;DR version.
Dr Kildall's wife, Barbara McEwen, was DR's lawyer. She negotiated with clients and suppliers, not the CEO who was a programmer.
IBM wanted an NDA which DR was unwilling to do. She said no. Remember DR was the industry giant in microcomputer OSes at this time, and IBM didn't have an offering at all.
Kildall was flying to visit an important client; this wasn't some accidental joyride.
This lie about Kildall literally drove him to drink and his early death. Stop repeating it. It's not funny or clever. It's an evil, vindictive lie.
Tom Rolander was the other passenger in the plane. Is his testimony good enough?
Listen to him describe the flight he was on.
