Ton Roosendaal (Dutch pronunciation: [tɔn roːsɛnˈdaːl]; born March 20, 1960) is a Dutch software developer. He is known as the original creator of the open-source 3D creation suite Blender, as chairman of the Blender Foundation, and for pioneering large scale open-content projects. In 2007 he established the Blender Institute in Amsterdam, where he works on coordinating Blender development, publishing manuals and DVD training, and organizing 3D animation and game projects.
Early years 
Roosendaal studied Industrial Design in Eindhoven, before founding the animation studio "NeoGeo" in 1989. It quickly became the largest 3D animation studio in the Netherlands. At NeoGeo, Roosendaal was responsible for software development, and in 1995 decided to start the development of an in-house software tool for 3D animation, based on the tools that NeoGeo had already written. This tool was later named "Blender". In January 1998, a free version of Blender was released on the internet, followed by versions for Linux and FreeBSD in April. Shortly after that, NeoGeo was taken over by an other company in parts. This was when Ton Roosendaal and Frank van Beek decided to found a company called Not a Number (NaN) to further market and develop Blender. NaN's business model involved providing commercial products and services around Blender. In 2000 the company secured growth financing by several investment companies. The target of this was to create a free creation tool for interactive 3D (online) content, and commercial versions of the software for distribution and publishing. Roosendaal moved to Amsterdam in 2002.
Due to low sales and the ongoing difficult economic climate, the NaN investors decided to shut down all operations in January/February 2002. This meant that the development of Blender would be ended. However, in May 2002, with support from the user community and customers, Ton Roosendaal founded the non-profit Blender Foundation.
Blender Foundation 
The Blender Foundation's first goal was to find a way to continue developing and promoting Blender as a community based open source project. In July 2002, NaN investors agreed on a plan to attempt to publish Blender under an open-source license using the Street Performer Protocol. The "Free Blender" campaign sought to raise 100,000 EUR as a one-time fee so that the NaN investors would agree on open sourcing Blender. The campaign reached this goal in only seven weeks. On Sunday 13 October 2002, Blender was therefore released under the terms of the GNU General Public License. After this success, Ton Roosendaal began to coordinate the development of Blender by volunteers as chairman of the Blender Foundation.
With Blender originating as an in-house creation tool, feedback from the use of the tool has fed into its ongoing development. In the first two and a half years of open source development, it was especially this unique attribute of the Blender project that has proved to be difficult to organize and maintain. Instead of funding the project directly by bringing together software developers, the Blender Foundation decided to start a project with the best artists within the Blender community and challenge them to make a 3D animated movie short. The goal of the project was to simultaneously prove that Blender can be used to create a professional quality animation, and to help the development of Blender itself.
Open-content projects 
In 2005, work on Project Orange began. The result of the project was the world's first widely recognized open movie, Elephants Dream. The movie and all assets used during production were published under the open Creative Commons Attribution license.
Because of the success of the first open movie project, Ton Roosendaal established the "Blender Institute" in summer 2007. It is now the permanent office and studio of the Blender Foundation, and is mainly used as an office for the full-time employees of the Blender Foundation and to coordinate and realize the Open Projects related to 3D movies, games and visual effects.
In April 2008 the Peach Project, the open movie Big Buck Bunny, was completed in the Blender Institute. In September 2008 the open game Yo Frankie! was released. The third open movie, Project Durian, also known as Sintel was released on 30 September 2010. He has recently finished a fourth project, titled Tears of Steel, and has already announced a Project Gooseberry to follow it in 2012–2014, both announced on Twitter on 10 January 2011.
