Vice president, Open Source Affairs
Michael Tiemann is a true open source software pioneer. He made his first major open source contribution more than 2 decades ago by writing the GNU C++ compiler, the first native-code C++ compiler and debugger. His early work led to the creation of leading open source technologies and the first open source business model.
In 1989, Tiemann's technical expertise and entrepreneurial spirit led him to co-found Cygnus Solutions, the first company to provide commercial support for open source software. During his 10 years at Cygnus, Tiemann contributed in a number of roles, from president to hacker, helping lead the company from fledgling start-up to an admired open source leader.
Tiemann serves on a number of boards, including the Open Source Initiative, GNOME Foundation, and Open Source for America. Tiemann also provides financial support to organizations that further the goals of software and programmer freedom, including the Free Software Foundation and the Electronic Frontier Foundation.
