Question: Who started the foundation that developed the Free Software Directory?

Knowledge 1: Free Software Directory
The Free Software Directory (FSD) is a project of the Free Software Foundation (FSF). It catalogs free software that runs under free operating systems - particularly GNU and Linux. The cataloged projects are often able to run in several other operating systems. The project was formerly co-run by UNESCO. [SEP] Knowledge 2: Richard Stallman
In 1985, Stallman published the GNU Manifesto, which outlined his motivation for creating a free operating system called GNU, which would be compatible with Unix. The name GNU is a recursive acronym for "GNU's Not Unix". Soon after, he started a nonprofit corporation called the Free Software Foundation to employ free software programmers and provide a legal infrastructure for the free software movement. Stallman is the nonsalaried president of the FSF, which is a 501(c)(3) nonprofit organization founded in Massachusetts. Stallman popularized the concept of copyleft, a legal mechanism to protect the modification and redistribution rights for free software. It was first implemented in the GNU Emacs General Public License, and in 1989 the first program-independent GNU General Public License (GPL) was released. By then, much of the GNU system had been completed.

In 1983, Richard Stallman, founder of the Free Software Foundation, set forth plans of a complete Unix - like operating system, called GNU, composed entirely of free software. In September of that year, Stallman published a manifesto in Dr. Dobb's Journal detailing his new project publicly, outlining his vision of free software. Software development work began in January 1984. By 1991, the GNU mid-level portions of the operating system were almost complete, and the upper level could be supplied by the X Window System, but the lower level (kernel, device drivers, system - level utilities and daemons) was still mostly lacking. The GNU kernel was called GNU Hurd. The Hurd followed an ambitious design which proved unexpectedly difficult to implement and has only been marginally usable.

The Free Software Definition written by Richard Stallman and published by Free Software Foundation (FSF), defines free software as being software that ensures that the end users have freedom in using, studying, sharing and modifying that software. The term "free" is used in the sense of "free speech," not of "free of charge." The earliest-known publication of the definition was in the February 1986 edition of the now-discontinued GNU's Bulletin publication of FSF. The canonical source for the document is in the philosophy section of the GNU Project website. , it is published there in 39 languages. FSF publishes a list of licences which meet this definition.
