I've seen college graduates who don't even know who Knuth is.
To be frank, no one really cares who Knuth is. Knuth infused computer science to the point where many classic algorithms are Knuth's and we just don't mention it. The shuffle algorithm is a good example of that, it is so classic that it seems to have existed since the dawn of time. The same effect happens with string search, most people will refer it as "string search", or "linear string search". Only people interested in the problem call it KMP; almost never I hear it called Knuth-Morris-Pratt.
Knuth is a legend, he is part of computer science.
