Thorsten Behrens

Chairman of the Board, TDF Founder, Hacker, OASIS ODF TC member, working on the code since 2001

Thorsten was part of the OpenOffice.org project almost from the start, when he joined the then-Sun-Microsystems development team back in early 2001. He’s a computer scientist by education, and a Free Software enthusiast by heart, a geek from early childhood - and someone who was lucky enough to turn a hobby into an occupation.

During his now ten years of tenure in the project, he’s spent most of his time hacking the code in areas ranging from build system, platform abstraction libraries, Impress and Writer.

During the last two years, Joel has focused on encouraging users to become more involved as contributors, as he is a firm believer that every user has the ability to contribute in making LibreOffice better for everyone. Joel represented QA on the ESC call for a year, helped organize bi-weekly QA calls, has had the chance to commit a few patches, and is actively trying to grow awareness of TDF in the United States Joel currently resides in San Diego, CA with his wife and is attaining his law degree.

Andreas Mantke


Andreas Mantke made his first experience with free software at the end of the 1990s when he started to use Linux and tried out some of the development packages of OpenOffice.org a bit later. He joined the free office suite project in 2002 and wrote some howto for the software. He got involved in different areas of the project, e.g. documentation and extensions website, and worked with the Portable team. Andreas supported the way to an independent foundation as the home for development of the office suite and its community and started working for LibreOffice and The Document Foundation on different areas since September 2010. He surfed as a (deputy) member on the Board of Directors at the Document Foundation since its establishment in February 2012. He worked for the infrastructure team of the foundation and attends many events on behalf of the foundation and LibreOffice.

Michael Meeks

VP of Productivity, Collabora

Michael is a Christian and enthusiastic believer in Free software. His long involvement with OpenOffice.org starts before it was open sourced, working with Sun to see how best to integrate it into the Linux Desktop. OpenOffice.org replaced his previous passion: the gnumeric spreadsheet and its interoperability. Michael has lead, and helped to grow OpenOffice.org investment through Ximian, Novell and SUSE. He has contributed code to many of the components of the suite, and is excited about the future of the code. He now leads Collabora’s Productivity division.

In other roles, he has contributed to MeeGo, GNOME, CORBA, Nautilus, Evolution and accessibility, amongst many other interesting things.

Before all this, he enjoyed working for Quantel gaining expertise in real time software and high performance custom hardware for real time Audio / Video editing and playback.

Even since long before that he is an open source enthusiast and did start with minor contributions to a range of open source projects.

Fridrich Štrba

Developer, Trained Monkey, GSoC Mentor

Fridrich is a Christian and enthusiastic participant in Free Software.
