Robert "Bob" Chassell was one of the founding directors of the Free Software Foundation (FSF).
Bob was born on 22 August 1946, in Bennington, VT. He read economics at Peterhouse, Cambridge University. [2]
In 1985, he became one of the founding directors of the FSF. While on the Board of Directors, he was also the treasurer for the FSF. [3] At this time, he started the Texinfo documentation system for GNU together with Richard Stallman.
He left the FSF to become a full-time speaker on free software topics. He was diagnosed with progressive supranuclear palsy (PSP) in 2010, and died as a result on 30 June 2017.
Chassell has authored several books including:
Free software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software regardless of how much is paid to obtain the program. Computer programs are deemed "free" if they give end-users ultimate control over the software and, subsequently, over their devices.
The Free Software Definition written by Richard Stallman and published by the 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 by the FSF. The canonical source for the document is in the philosophy section of the GNU Project website. As of April 2008, it is published there in 39 languages. The FSF publishes a list of licences which meet this definition.
GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public License (GPL).
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications.
XEmacs is a graphical- and console-based text editor which runs on almost any Unix-like operating system as well as Microsoft Windows. XEmacs is a fork, based on a version of GNU Emacs from the late 1980s. Any user can download, use, and modify XEmacs as free software available under the GNU General Public License version 2 or any later version.
Gosling Emacs is a discontinued Emacs implementation written in 1981 by James Gosling in C.
The GNU Project is a free software, mass collaboration project that Richard Stallman announced on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and computing devices by collaboratively developing and publishing software that gives everyone the rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in its license.
Texinfo is a typesetting syntax used for generating documentation in both on-line and printed form with a single source file. It is implemented by a computer program released as free software of the same name, created and made available by the GNU Project from the Free Software Foundation.
Within the free software and the open-source software communities there is controversy over whether to refer to computer operating systems that use a combination of GNU software and the Linux kernel as "GNU/Linux" or "Linux" systems.
Richard Matthew Stallman, also known by his initials, rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in a manner such that its users receive the freedoms to use, study, distribute, and modify that software. Software that ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation, developed the GNU Compiler Collection and GNU Emacs, and wrote the GNU General Public License.
Leonard "Len" H. Tower Jr. is a free software activist and one of the founding board members of the Free Software Foundation, where he contributed to the initial releases of gcc and GNU diff. He left the Free Software Foundation in 1997.
Loïc Dachary is a French free software developer and activist who has been active since 1987. Dachary currently contributes to free software projects and acts as president of the Free Software Foundation in France. He is a speaker for the GNU Project and the April association. Right now, he is a full-time volunteer for the SecureDrop project.
William John Sullivan is a software freedom activist, hacker, and writer. John is currently executive director of the Free Software Foundation (FSF), where he has worked since early 2003. He is also a speaker and webmaster for the GNU Project. He also maintains the Plannermode and delicious-el packages for the GNU Emacs text editor.
GNU Emacs is a free software text editor. It was created by GNU Project founder Richard Stallman. In common with other varieties of Emacs, GNU Emacs is extensible using a Turing complete programming language. GNU Emacs has been called "the most powerful text editor available today". With proper support from the underlying system, GNU Emacs is able to display files in multiple character sets, and has been able to simultaneously display most human languages since at least 1999. Throughout its history, GNU Emacs has been a central component of the GNU project, and a flagship of the free software movement. GNU Emacs is sometimes abbreviated as GNUMACS, especially to differentiate it from other EMACS variants. The tag line for GNU Emacs is "the extensible self-documenting text editor".
Emacs or EMACS is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on its direct descendant, GNU Emacs, continues actively as of 2021.
Copyleft is the practice of granting the right to freely distribute and modify intellectual property with the requirement that the same rights be preserved in derivative works created from that property. Copyleft in the form of licenses can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents.
The GNU General Public License is a series of widely used free software licenses that guarantee end users the freedom to run, study, share, and modify the software. The licenses were originally written by Richard Stallman, founder of the Free Software Foundation (FSF), for the GNU Project, and grant the recipients of a computer program the rights of the Free Software Definition. The GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. This is in distinction to permissive software licenses, of which the BSD licenses and the MIT License are widely used, less restrictive examples. GPL was the first copyleft license for general use.
The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985, to support the free software movement, which promotes the universal freedom to study, distribute, create, and modify computer software, with the organization's preference for software being distributed under copyleft terms, such as with its own GNU General Public License. The FSF was incorporated in Boston, Massachusetts, US, where it is also based.
Free Software, Free Society: Selected Essays of Richard M. Stallman is a collection of writings by Richard Stallman. It introduces the subject of history and development of the GNU Project and the Free Software Foundation, explains authors philosophical position on Free Software movement, deals with the topics of software ethics, copyright and patent laws, as well as business practices in application to computer software. The author proposes Free software licenses as a solution to social issues created by proprietary software and described in essays.
