Ah, it's time for my favorite part of this forum again: Nitpicking about computer history.

That is not quite right.

For example, Multics - the collaboration between General Electric, the MIT and the Bell Labs which was still actively being developed when Ken Thompson started his then-unnamed Unix project - was written in PL/I, which I would consider a "high-level" language. Granted, there was some assembly code somewhere in Multics, but that was and is also true for Unix. DTSS, another operating system that predates Unix by a few years, was reportedly written in BASIC, ALGOL et cetera.

I think that these two examples are enough for now ... :-)

Yes and no.

Unix was first designed and implemented by Ken Thompson who also derived the B language from BCPL which would later become C. A couple of other people from the Bell Laboratories, notably Douglas McIlroy and Brian Kernighan, joined his efforts. C was mostly invented by Dennis Ritchie in 1972, the fourth Unix version was the first one that was rewritten in it.

It was one team - but not everyone worked on everything at the same time.

Personal note: And I think we should finally take it to the next step.
