1Maxima's development history spans three distinct periods: The 2research project at MIT, the stewardship of William Schelter and the 3current Maxima project. 4 5MACSYMA (Project MAC's SYmbolic MAnipulation System) was developed by 6the Mathlab group of the MIT Laboratory for Computer Science 7(originally known as Project MAC), during the years 1969-1972. Their 8work was supported by grants NSG 1323 of the National Aeronautics and 9Space Administration, N00014-77-C-0641 of the Office of Naval 10Research, ET-78-C-02-4687 of the U.S. Department of Energy, and 11F49620-79-C-020 of the U.S. Air Force. MACSYMA was further modified 12for use under the UNIX operating system (for use on DEC VAX computers 13and Sun workstations), by Richard Fateman and colleagues at the 14University of California at Berkeley; this version of MACSYMA is known 15as VAXIMA. 16 17William Schelter developed and maintained this version, Maxima, from 18the project's inception until his untimely death in 2001. We are 19eternally grateful for his enormous contribution. 20 21William Schelter thanked the following people for having tested 22the code under various common lisp implementations, and for helpful 23comments: 24 25hagiya%kurims.kurims.kyoto-u.junet%utokyo-relay.csnet@RELAY.CS.NET 26 (in kcl aosv) 27steve@spock.ncsa.uiuc.edu (Steve on sun/franz common lisp) 28spar!malcolm@decwrl.dec.com (malcolm) sun/lucid 29raible@orville.nas.nasa.gov (Eric Raible on iris(kcl)) 30fateman@peoplesparc.Berkeley.EDU (Richard Fateman) 31 32In November, 2001, the Maxima project moved to the Sourceforge 33project hosting site. 34 35As of April 2007, the Maxima developers are: 36 37James Amundson 38Jorge Barros de Abreu 39Jay Belanger 40David Billinghurst 41Marco Ciampa 42Douglas Crosher 43Robert Dodier 44Andreas Eder 45Andrey Grozin 46Yasuaki Honda 47Stavros Macrakis 48Camm Maguire 49Volker van Nek 50Mario Rodriguez Riotorto 51Juan Pablo Romero Bernal 52Dan Stanger 53Viktor Toth 54Raymond Toy 55Jaime Villate 56Andrej Vodopivec 57Barton Willis 58Cliff Yapp 59Vadim V.

Russ 89Marek Rychlik 90Gunter K�nigsmann 91Wolfgang Dautermann 92 93Starting with version 5.9.0, Maxima uses mk::defsystem and (slightly 94modified) run-lisp from the Common Lisp Open Code Collection, 95<http://clocc.sourceforge.net>. 96 97The nregex code was written by Lawrence E. Freil. 98
