Bell Labs
From 1960 until 1986, Morris was a researcher at Bell Labs and worked on Multics and later Unix. Morris's contributions to early versions of Unix include the math library, the bc programming language, the program crypt, and the password encryption scheme used for user authentication. The encryption scheme was based on using a trapdoor function (now called a key derivation function) to compute hashes of user passwords which were stored in the file /etc/passwd; analogous techniques, relying on different functions, are still in use today.

Famous quotes containing the word bell:
“I can entertain the proposition that life is a metaphor for boxing—for one of those bouts that go on and on, round following round, jabs, missed punches, clinches, nothing determined, again the bell and again and you and your opponent so evenly matched it’s impossible not to see that your opponent is you.... Life is like boxing in many unsettling respects. But boxing is only like boxing.”
—Joyce Carol Oates (b. 1938)
