David Nolan, American activist and politician (d. 2010)
David Fraser Nolan (; November 23, 1943 – November 21, 2010) was an American activist and politician. He was one of the founders of the Libertarian Party of the United States, having hosted the meeting in 1971 at which the Party was founded. Nolan subsequently served the party in a number of roles including National Committee Chair, editor of the party newsletter, Chair of the By-laws Committee, Chair of the Judicial Committee, and Chair of the Platform Committee.
He is also known as the inventor of the Nolan Chart, an attempt to improve on the left versus right political taxonomy by separating the issues of economic freedom and social freedom and presenting them on a two-dimensional plane instead of the traditional line. Decades after its introduction, it continues to be popular, with millions of copies having been distributed, including by the group Advocates for Self-Government as the "World's Smallest Political Quiz".
