In 1983, Nelson co-wrote a MacPaint clone, Painter's Apprentice with Patrick Naughton. Nelson was the original developer of Freemacs (a variant of Emacs used by FreeDOS). While attending university, Nelson began developing the collection of drivers later commercially released as the "Crynwr Collection". In 1991, he founded Crynwr Software, a company dedicated to creating bulk e-mail software, located in Potsdam, New York.
In 1998, Nelson became one of the first group to serve on the Board of Directors of the Open Source Initiative, joining Brian Behlendorf, Ian Murdock and Chip Salzenberg. In February 2005, he became the President of the Open Source Initiative, but resigned a few days later, on February 23, 2005, because a posting on his personal blog was deemed to be racist. Nelson apologized to those who perceived the post, which he withdrew because it "was not well written", as racist, and indicated that he did not believe himself to be politically savvy enough for the role of president. Six years later, in March 2011, he departed the Board due to term limits on the position.
Nelson is the son of Russell Edward Nelson and Gladys Jacobsen Nelson.  He is a Quaker and is credited with developing the first Quaker-themed website in the world. Nelson is a pacifist, and a member of the Libertarian Party of the United States.
