Benjamin Mako Hill

Benjamin Mako Hill is a social scientist, technologist, and activist. In all three roles, he works to understand why some attempts at peer production — like Wikipedia and GNU/Linux — build large volunteer communities while the vast majority never attract even a second contributor. He is an Assistant Professor in the Department of Communication at the University of Washington. He is also a faculty affiliate at the Berkman Center for Internet and Society and an affiliate at the Institute for Quantitative Social Science — both at Harvard University. He has also been a leader, developer, and contributor to the free software community for more than a decade as part of the Debian and Ubuntu projects. He is the author of several best-selling technical books, a member of the Free Software Foundation board of directors and an advisor to the Wikimedia Foundation. Hill has a Masters degree from the MIT Media Lab and a PhD from MIT in an interdepartmental program between the Sloan School of Management and the Media Lab.

Richard Stallman

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.
