Richard Stallman founded the free software movement in 1983 when he announced he would develop the GNU operating system, a Unix-like operating system meant to consist entirely of free software. He has been the GNU project's leader ever since. In October 1985 he started the Free Software Foundation.

Since the mid-1990s, Stallman has spent most of his time in political advocacy for free software, and spreading the ethical ideas of the movement, as well as campaigning against both software patents and dangerous extension of copyright laws. Before that, Richard developed a number of widely used programs that are components of GNU, including the original Emacs, the GNU Compiler Collection, the GNU symbolic debugger (gdb), GNU Emacs, and various others.

Seth Schoen has worked at the Electronic Frontier Foundation for over a decade, creating the Staff Technologist position and helping other technologists understand the civil liberties implications of their work, EFF staff better understand technology related to EFF's legal work, and the public understand what products they use really do. He helped create the LNX-BBC live CD and has researched phenomena including laser printer forensic tracking codes, ISP packet spoofing, and key recovery from computer RAM after a computer has been turned off. He has testified before the U.S. Copyright Office, U.S. Sentencing Commission, and in several courts.
