The authors of TeXmacs

The GNU TeXmacs system, which is part of the GNU project, was designed and written by Joris van der Hoeven. The system was inspired both by the TeX system, written by D. Knuth, and by Emacs, written by R. Stallman. Special thanks goes to them, as well as to the C.N.R.S. (the French national institute for scientific research), which employs me and authorized me to freely distribute this program. Further thanks go to the contributors below.
