Scott Elliott Fahlman (born March 21, 1948) is a computer scientist and Professor Emeritus at Carnegie Mellon University. He is notable for early work on automated planning in a blocks world, on semantic networks, on neural networks (and, in particular, the cascade correlation algorithm), on the Dylan programming language, and on Common Lisp (in particular CMU Common Lisp and he was one of the founders of Lucid Inc.). During the period when it was standardized, he was recognized as "the leader of Common Lisp."[1] Recently, Fahlman has been engaged in constructing a knowledge base, "Scone", based in part on his thesis work on the NETL Semantic Network.[2]

Life and career

Fahlman was born in Medina, Ohio, the son of Lorna May (Dean) and John Emil Fahlman.[3] He received his bachelor's degree and master's degree in 1973 from MIT, and his Ph.D. from MIT in 1977. His Master's thesis advisor was Patrick Winston and his doctoral thesis advisor was Gerald Sussman.[4] He has noted that his doctoral diploma says the degree was awarded for "original research as demonstrated by a thesis in the field of Artificial Intelligence" and suggested that it may be the first to use that term.[5] He is a fellow of the American Association for Artificial Intelligence.

Fahlman acted as thesis advisor for Donald Cohen, David B. McDonald, David S. Touretzky, Skef Wholey, Justin Boyan, Michael Witbrock, and Alicia Tribble Sagae.

From May 1996 to July 2001, Fahlman directed the Justsystem Pittsburgh Research Center.

Emoticons

Fahlman is credited with originating the first smiley emoticon,[6][7][8] which he thought would help people on a message board at Carnegie Mellon to distinguish serious posts from jokes. He proposed the use of :-) and :-( for this purpose, and the symbols caught on. The original message from which these symbols originated was posted on September 19, 1982. The message was recovered by Jeff Baird on September 10, 2002[9] and is quoted:

19-Sep-82 11:44    Scott E  Fahlman             :-)
From: Scott E  Fahlman <Fahlman at Cmu-20c>

I propose that the following character sequence for joke markers:

:-)

Read it sideways.  Actually, it is probably more economical to mark
things that are NOT jokes, given current trends.  For this, use

:-(

Though credited with originating the smiley emoticons, he was not the first emoticon user; a similar marker appeared in an article of Reader's Digest in May 1967.[10] In an interview printed in the New York Times in 1969, Vladimir Nabokov noted, "I often think there should exist a special typographical sign for a smile — some sort of concave mark, a supine round bracket."[11]
