Okay, I know you all know who Donald Knuth is, but just to waste some bandwidth, I’ll provide his background anyway:
Knuth wrote The Art Of Computer Programming, considered the Bible of computer programming for those with an academic background. I remember seeing the beige, hard-cover volumes at MUN‘s book store for graduates, yet I bought them as a 1st year student because they were so damn interesting. They’re not light reading.
Besides The Art of Computer Programming, he’s noted as the creator of TeX (computer science and mathematics students should know about that), a typesetting system, and providing a reward for any mistakes found in his published books.
Oh, and his name is pronounced “Ka-nooth” – the “K” is not silent.
