[These notes are based on various sources, including the historical data in Don Walker's 1982 panel contribution (see below).] ACL was founded in 1962, but was then named AMTCL, standing for Association for Machine Translation and Computational Linguistics. It became the ACL in 1968. In the first year or two membership seems to have been about 100. There was a journal `Mechanical Translation and Computational Linguistics', a renaming of the journal `MT: Mechanical Translation' which had been founded in 1954 and was taken over by AMTCL in 1965. This journal was succeeded by AJCL ('American Journal of Computational Linguistics') which was published for ACL in microfiche form only from 1974-1978. This was in turn succeeded by the paper version of AJCL, starting from 1980 with initial volume 6, renamed `Computational Linguistics' in 1984. This was first produced with George Heidorn as Editor through IBM and was subsequently edited by James Allen and then Julia Hirschberg. It has been been published by MIT Press since 1988. The list of Presidents is as follows: 1962 (no President within this first half year) 1963 Vic Yngve 1964 +David Hays 1965 Winfred Lehmann 1966 +Paul Garvin 1967 Susumo Kuno 1968 +Don Walker 1969 Martin Kay 1970 Warren Plath 1971 Joyce Friedman 1972 +Robert Simmons 1973 Robert Barnes 1974 Bill Woods 1975 Aravind Joshi 1976 Stan Petrick 1977 Paul Chapin 1978 Jonathan Allen 1979 Ron Kaplan 1980 Bonnie Webber 1981 Norm Sondheimer 1982 Jane Robinson 1983 Ray Perrault 1984 Martha Evens 1985 Madeleine Bates 1986 Ralph Weischedel 1987 William Mann 1988 Alan Biermann 1989 Candy Sidner 1990 Jerry Hobbs 1991 Ralph Grishman 1992 Kathy McKeown 1993 Fernando Pereira 1994 Karen Sparck Jones 1995 Doug Appelt 1996 Oliviero Stock 1997 Mitch Marcus 1998 Eva Hajicova 1999 Phil Cohen 2000 Wolfgang Wahlster 2001 Eduard Hovy 2002 John Nerbonne The (Secretary)-Treasurer from 1963-1971 was Harry Josselson; from 1972-1976 it was Hood Roberts and from 1976-1993 Don Walker was Secretary-Treasurer. Kathy McKeown became Secretary-Treasurer in 1994, Kathy McCoy in 1998, and Sandra Carberry Secretary in 2001. The AMTCL had its first meeting in 1963. Early meetings were relatively modest, sometimes in conjunction with other organisations, with panels, and with conference handbooks containing only abstracts. The annual conference became more substantial during the 1970s, with proper Proceedings including papers at least from 1979. The meeting became well established during the 1980s, with rigorous refereeing and a high standing in the field. The first meeting outside North America was in Madrid in 1997. There was a 20th Anniversary Panel at the 1982 Meeting, as follows: PANEL: REFLECTIONS ON 20 YEARS OF THE ACL Reflections on 20 Years of the ACL: An Introduction Donald E. Walker, Chair Our Double Anniversary Victor H. Yngve 2002: Another Score David G. Hays My Term Winfred P. Lehmann A Society in Transition Donald E. Walker Themes from 1972 Robert F. Simmons Twenty Years of Reflections Aravind Joshi ACL in 1977 Paul G. Chapin Reflections on Twenty Years of the ACL Jonathan Allen On the Present Norman K. Sondheimer (There is interesting material in the panel papers.) The 30th Anniversary in 1992 was marked by a birthday cake at the Banquet, and Don Walker's invited talk, `Reflections and Projections', at the 1992 meeting also included a lot of historical detail (the transparencies from this may still exist in the files). There was also a Panel `After 25 years: Directions for Natural Language Processing' at the 1987 meeting, with J Carbonell, B Grosz, M Marcus, J Pierrehumbert and R Weischedel. There has been a European Chapter with its own officers since 1982, with biennial conferences beginning in 1983. In 2000 a North American Chapter was formed, also with its own officers and conferences (the first in 2000). ACL itself thus became a top-level organisation, reflecting its increasingly international status and role. ACL has at intervals held joint conferences with e.g. COLING, and has sponsored Applied NLP Conferences. It has developed Special Interest Groups and included Tutorials and hosted many sponsored Workshops at its annual meetings.
