Ben Fry and Casey Reas are the co-founders of Processing and the primary designers of the language and software. The full Processing team leading the current push from Processing BETA to version 1.0 consists of:

Tom Carden (Processing Hacks Master HACK3R)
Florian Jenett (Design Director + Net Burgermeister)
Andreas Schlegel (Librarian)
This list will grow...

The core Processing software is augmented by libraries contributed through the community. Inventive libraries are the bright future of this project. A list of developers and their libraries is maintained here. This contribution can't be underestimated.

Processing was started in Fall 2001 by Ben and Casey. Over the years, a growing number of people have been making additional contributions to the project. (See the list below.) The current state of Processing would not be possible without this shared effort. The Processing software is a community effort. It has evolved through a continuous conversation.

We're always looking for people to join in and with the coming release of Processing version 1.0. We hope to distribute the development of the project among a small group of dedicated individuals.

We give a special "Thank You!" to Sami Arola for writing the base of P3D, Simon Greenwold for incorporting camera and lights into P3D, and Florian Jenett for years of faithful service on the website.

Processing was first introduced to students through workshops. We're eternally grateful to the first institutions who took a chance on our new software in 2001 and 2002: Musashino Art University (Tokyo), ENSCI Les Atelier (Paris), HyperWerk (Basel), Royal Conservatory (Hague). Many universities have integrated Processing into their curriculum and we're grateful to the pioneer faculty members and students at these institutions. They are too numerous to mention here. The students and faculty in New York University's Interactive Telecommunication Program (ITP) deserve a special thank you for their early adoption and promotion.

We also thank the Open Source software developers of Jikes, JEdit, ORO Matcher, and ANTLR. The Processing software is built upon their work.
