Thanks are due to the AIAI for being willing to release wxWindows into the public domain, and to my wife Harriet Smart for her patience while I worked on wxWindows after hours.
The Internet has been an essential prop when coming up against tricky XView, Motif and MS Windows problems. Thanks to those who answered my queries or submitted bug fixes and enhancements; wxWindows is very much a team effort.
Hermann Dunkel contributed XPM support; Arthur Seaton wrote the memory checking code; Olaf Klein and Patrick Halke wrote the ODBC classes; Harri Pasanen and Robin Dunn wrote wxPython and contributed to the wxExtend library.
Markus Holzem write the excellent Xt port. Jonathan Tonberg, Bill Hale, Cecil Coupe, Thomaso Paoletti, Thomas Fettig, and others slaved away writing the Mac port. Keith Gary Boyce ported wxWindows to the free GNU-WIN32 compiler, refusing to give up when I suggested taking shortcuts.
Many thanks also to: Timothy Peters, Jamshid Afshar, Patrick Albert, C. Buckley, Robin Corbet, Harco de Hilster, Josep Fortiana, Torsten Liermann, Tatu Männistö, Ian Perrigo, Giordano Pezzoli, Petr Smilauer, Neil Smith, Kari Systä, Jyrki Tuomi, Edward Zimmermann, Ian Brown, and many others.
