That's the line breaker, which is an important contributor to the
quality of TeX output.
But TeX's *hyphenation* algorithm per se was invented by Franklin Mark
Liang and was indeed considerably better than its predecessors and
competitors (including most or all commercial typesetting software --
which was a big part of the motivation for it):

I hadn't realized that groff hyphenation had been taken from
Tex, not troff. Is that becuase Tex did a better job, or
because troff's was deemed proprietary?
Given the author, I would guess the later as he wanted to be FOSS and
would not have looked at the ditroff source - but that guess is worth
just that ;-)
I remembered reading about Knuth's line-breaking algorithm in
Software Practice & Experience in early eighties and being quite
impressed with it. So may be that clear description of the algorithm
has something to do with it? Ah, here it is:
