«I propose the following character sequence for joke markers: :-) Read it sideways.»

Carnegie Mellon bulletin board post, 19 September 1982

Scott Fahlman works on knowledge representation and neural networks, but is best known for a single message board post in 1982 suggesting that :-) and :-( be used to mark jokes and serious remarks. Every emoji in use today descends from that suggestion.

Key achievements

  • Invented the emoticon in a bulletin board post, 1982
  • Created the Cascade-Correlation neural network learning algorithm
  • Co-authored Common Lisp, a standard of the language

Universities

  • Pittsburgh, Pennsylvania

    Research professor in the computer science department, where he proposed the smiley in 1982.

  • Cambridge, Massachusetts

    Took his bachelor's, master's and PhD degrees at MIT, finishing in 1977 in artificial intelligence.

Facts

  • The original 1982 post was recovered from backup tapes twenty years later after a long search through old archives.
  • He proposed the smiley to solve a real problem: people on the department bulletin board kept mistaking jokes for serious warnings.
  • He has said he dislikes the graphical emoji that replaced the typed original, preferring the sideways version.
