Linux, on the other hand, was a complete reimplementation
from scratch. Linus Torvalds wanted something that took
better advantage of his hardware than Minix, the teaching
system by Andy Tannenbaum that he had been running. Linux
took a far more traditional approach to building a Unix-like
system, in that it's a monolithic kernel (the kernel exists
in a single address space), while Minix is a microkernel
(services are logically distinct and isolated from one
another, and communicate via message-passing). Famously,
Tannenbaum took Torvalds to task for this decision, declaring
Linux obsolete before it was finished. Of course, it is now,
by far, the most popular and important operating system in
the world.

I just kept the Linux part as quotation but the whole story is just amazing reading! All such stories deserve separate thread!
