Background and career
Lawrence Mark Sanger (born July 16, 1968) is an American Internet project developer and philosopher who co-founded Wikipedia with Jimmy Wales. Sanger coined the name Wikipedia and provided initial drafts for many of its early guidelines, including the "Neutral point of view" and "Ignore all rules" policies. Prior to Wikipedia, he was the editor-in-chief of Nupedia, an online encyclopedia which was the predecessor of Wikipedia. He later worked on other encyclopedic projects, including the Encyclopedia of Earth, Citizendium, Everipedia, and Ballotpedia. Sanger's other interests include theology and philosophy such as epistemology, early modern philosophy, and ethics. He taught philosophy at Ohio State University. Sanger joined the online encyclopedia Nupedia as editor-in-chief in 2000. Disappointed with the slow progress of Nupedia, Sanger proposed using a wiki to solicit and receive articles to put through Nupedia's peer-review process; this change led to the development and launch of Wikipedia in 2001. Sanger continued to serve as Nupedia's editor-in-chief and as an active contributor to Wikipedia in its first year, but he was laid off and left the project in March 2002. Sanger's status as a co-founder of Wikipedia has been questioned by Wales, but is generally accepted. Since Sanger's departure from Wikipedia, he has been critical of the project, describing it in 2007 as being "broken beyond repair". He has argued that Wikipedia lacks credibility and accuracy because, in his view, it had a lack of respect for expertise. Since 2020, he has accused Wikipedia of having a left-wing ideological bias in its articles. Sanger's effort to change Wikipedia was received negatively by editors of the English Wikipedia. In June 2026, he was banned from editing the English Wikipedia after the community determined that he had violated its "canvassing", or brigading, rule by publicizing an internal community discussion on his proposed "WikiProject Intellectual Diversity" to his 93,000 followers on X. The community also concluded that he was "not here" to constructively build the encyclopedia. In 2006, Sanger founded Citizendium to compete with Wikipedia; in 2010, he stepped down as editor-in-chief, and in 2020, he left Citizendium entirely. In 2017, he joined Everipedia as chief information officer (CIO). He resigned in 2019, to establish the Knowledge Standards Foundation and the "encyclosphere". As of 2023, Sanger was serving as the executive director of the Knowledge Standards Foundation.
Lawrence Mark Sanger was born in Bellevue, Washington, on July 16, 1968. His father, Gerry, was a marine biologist who studied seabirds and worked for the United States Fish and Wildlife Service. His mother, Lana, was a homemaker. When he was seven years old, Sanger's family moved to Anchorage, Alaska, where he was raised. As a teenager, he played the violin and created a text-based adventure game using the programming language BASIC. Sanger later recalled, "I decided I wanted to study philosophy and make it my life's work when I was about 16". When he was 17 years old, Sanger, inspired by the works of René Descartes, began to believe "only the things that he could directly perceive or that could be logically derived from what he perceived".
In high school, Sanger played piano, did cross country running and cross-country skiing, was a champion debater, and completed his graduation requirements a year early. According to The Atlantic, Sanger "excelled in high school" and "fits the profile of almost every Internet early adopter: he’d been a good student, played Dungeons & Dragons, and tinkered with PCs as a youth". After graduating from high school he enrolled at Reed College, beginning in the fall of 1986, majoring in philosophy.
In college, Sanger became interested in the Internet and its potential as a publishing outlet. He set up a listserver as a medium for students and tutors to meet for tutoring and "to act as a forum for discussion of tutorials, tutorial methods, and the possibility and merits of a voluntary, free network of individual tutors and students finding each other via the Internet for education outside the traditional university setting". He started and moderated a libertarian philosophy discussion list, the Association for Systematic Philosophy. In 1994, Sanger wrote a manifesto for the discussion group:The history of philosophy is full of disagreement and confusion. One reaction by philosophers to this state of things is to doubt whether the truth about philosophy can ever be known, or whether there is any such thing as the truth about philosophy. But there is another reaction: one may set out to think more carefully and methodically than one's intellectual forebears. Sanger graduated from Reed College with a Bachelor of Arts in philosophy in 1991. He then pursued graduate studies at Ohio State University, where he earned his Master of Arts in philosophy in 1995 and his Ph.D. in philosophy in 2000. He is a professional epistemologist. His doctoral dissertation, completed under the philosopher George Pappas, was titled, Epistemic Circularity: An Essay on the Problem of Meta-Justification. Around 1994, Sanger met Jimmy Wales after subscribing to Wales's mailing list, "Moderated Discussion of Objectivist Philosophy" (MDOP). Beginning in 1998, Sanger and a friend ran a website called "Sanger and Shannon's Review of Y2K News Reports", a resource for people, such as managers of computer systems, concerned about the year 2000 problem.
Nupedia was a web-based encyclopedia whose articles were written by volunteer contributors possessing relevant subject matter expertise and reviewed by editors prior to publication, and were licensed as free content. It was conceived by Jimmy Wales and underwritten by his company Bomis. Wales had interacted with Sanger on mailing lists. In January 2000, Sanger had e-mailed Wales and others about a potential "cultural news blog" project that would cover social and political issues that he had in mind after January 1, 2000, had passed and rendered his Y2K site obsolete. Wales replied with "Instead of doing that, why don't you come and work on this idea that I've had?", presented the idea of Nupedia to Sanger, and invited him to join the project. Sanger was hired as Nupedia's editor-in-chief. He began to oversee Nupedia in February 2000, developing a review process for articles and recruiting editors. Through working on Nupedia, Sanger "found that it was a fascinating problem to organize people online to create encyclopedias". Articles were reviewed through Nupedia's email system before being posted on the site. Nupedia made very slow progress and was at a standstill at the end of 2000, causing consternation to Sanger and Wales, with Sanger saying that "by the summer of 2000, it had become clear that the process we tested out [for making articles on Nupedia] was very slow." In January 2001, Sanger proposed the creation of a wiki to speed article development, which resulted in the launch of Wikipedia on January 15, 2001. Wikipedia was initially intended as a collaborative wiki for which the public would write entries that would then be fed into Nupedia's review process. However, the majority of Nupedia's experts and the Nupedia advisory board wanted little to do with the project, with members of the Nupedia advisory board mailing list dismissing the idea of Wikipedia as being ridiculous. The idea of using a wiki came when Sanger met up with his friend Ben Kovitz for dinner on January 2, 2001, when Sanger was first introduced to wiki software. Kovitz, whom Sanger had known from philosophy mailing lists, was a computer programmer who had come across Ward Cunningham's Wiki. Sanger was impressed with the possibilities offered by wikis and called Wales, who agreed to try it. Sanger originated the name "Wikipedia", chosen from "a long list of names", which he later said was "a silly name for what was at first a very silly project". Sanger created Wikipedia's first introductory pages and home pages, and invited the first few people to make contributions to the website, which was then called the Nupedia Wiki. Within a few days of its launch, Wikipedia had outgrown Nupedia and a small community of editors had gathered. Sanger served as Wikipedia's "chief organizer", inviting new contributors and drafting early policy, including "Ignore all rules", "Neutral point of view", "No original research", and "Verifiability". He embraced Wikipedia's encouragement of boldness among its editors, telling users to "not worry about messing up". Sanger created the concept of "Brilliant prose", which evolved into featured articles as a way to showcase Wikipedia's highest-quality articles. Sanger soon grew disillusioned with Wikipedia, saying by mid-2001 its community was being "overrun" by "trolls" and "anarchist-types", who were "opposed to the idea that anyone should have any kind of authority that others do not". While such issues were not important to Sanger when Wikipedia was a source of articles for Nupedia, as it grew into an independent project he started to become more concerned about the community. Sanger came into conflict with Wikipedia editors who did not appreciate his modes of organization and exercising authority, including The Cunctator, another active early editor. Sanger responded to these conflicts by proposing a stronger emphasis on expert editors and giving certain contributors the authority to resolve disputes and enforce rules. He also asked to be given more respect and deference by Wikipedians, which backfired and led to an increase in friction between him and the community. Sanger was the only editorial employee of Wikipedia. In early 2002, Bomis announced the possibility of placing advertisements on Wikipedia, in part to pay for Sanger's employment, but the project was opposed to any commercialization and the market for Internet advertising was small. Sanger was laid off in February 2002 after Bomis lost a grant in the Dot-com crash, and he resigned as editor-in-chief of Nupedia and chief organizer of Wikipedia on March 1. Sanger said he ended his participation in Wikipedia and Nupedia as a volunteer because he could not do justice to the tasks as a part-timer, he was frustrated by sustained arguments, and while he cared about the project, it was "not something [he] would have chosen as a hobby" and he would rather spend time with family, "reading and writing philosophy, and playing fiddle". In a post to the Wikipedia community, Sanger said that his departure from Nupedia might not be permanent if funds were found for it again in the future. Sanger attempted to revive Nupedia throughout 2002 as its activity petered out. He tried to find an organization that would take control of it because it appeared Bomis and Wales seemed uninterested in managing it. Sanger also inquired about purchasing the domain and other proprietary materials from Bomis. He said Nupedia's demise was not entirely due to the inherent inefficiencies in its review process. The Nupedia server crashed in September 2003 and the site was never relaunched.
Sanger's role in co-founding or organizing Wikipedia was the subject of edits by Wales to Wikipedia articles in 2005. Sanger subsequently accused Wales of "rewriting history" by disregarding his involvement; Wales told Wired that he had only clarified details about Sanger's contribution to the project and removed factual errors, adding that he should not have done so. Wales later stated he had initially heard of the wiki concept from Bomis employee Jeremy Rosenfeld rather than Sanger. He also characterized Sanger's claim to be a co-founder as "absurd" and stated, "I know of no one who was there at the company at the beginning who would think it anything other than laughable." On his personal website, Sanger posted several links to support his role as a co-founder. As early as January 17, 2001, Sanger was cited as "Instigator of Nupedia's wiki" by active volunteer and chief copyeditor Ruth Ifcher, and he was identified as a co-founder of Wikipedia in September 2001 media reports. Sanger has said he organized Wikipedia while Wales was mostly focused on Bomis.com.
