Richard Stallman
Free Software Foundation

Richard Matthew Stallman is a software developer and software freedom activist. Born in 1953, he attended Harvard starting in 1970 and graduated in 1974 with a Bachelor of Arts in physics. From September 1974 to June 1975 he was a graduate student in physics at MIT.

He worked at the Artificial Intelligence Lab at MIT from 1971 to 1984, learning operating system development by doing it, except for the year he was a graduate student. He wrote the first extensible Emacs text editor there in 1976, and developed the AI technique of dependency-directed backtracking, also known as truth maintenance.

In 1983 Stallman announced the project to develop the GNU operating system, a Unix-like operating system meant to be entirely free software, and has been the project’s leader ever since. With that announcement he also launched the Free Software Movement.

Stallman began working on this project on January 5, 1984, resigning from MIT employment in order to do so. In October 1985 he started the Free Software Foundation, of which he is president as a full-time volunteer.

Spike Brehm
Software Engineer

Spike Brehm is a Software Engineer specializing in rich JavaScript apps at Airbnb. In over a decade of experience with JavaScript, he has seen its role on the web morph from novelty to basic building block.
