Oulipo (French pronunciation: [ulipo], short for French: Ouvroir de littérature potentielle; translated as "workshop of potential literature," stylized as OuLiPo) is a group of mainly French-speaking writers and mathematicians who create works using specific writing rules. It was started in 1960 by Raymond Queneau and François Le Lionnais. Other important members include novelists Georges Perec and Italo Calvino, poets Oskar Pastior and Jean Lescure, and poet/mathematician Jacques Roubaud.

The group explains "littérature potentielle" as (roughly translated): "searching for new structures and patterns that writers can use in any way they like." Queneau described Oulipians as "rats who build a labyrinth they plan to escape."

Writing rules are used to help create ideas and inspiration. For example, Perec used a "story-making machine" to write his book Life: A User's Manual. The group uses existing techniques, such as lipograms (A Void by Perec) and palindromes, and also invents new methods, often based on math problems, like the knight's tour on a chessboard or permutations.

History

Oulipo was created on November 24, 1960, as a group within the Collège de 'Pataphysique and was first called Séminaire de littérature expérimentale. At their second meeting, the group changed its name to Ouvroir de littérature potentielle, or Oulipo, based on a suggestion by Albert-Marie Schmidt. The idea for the group began in September 1960, when a small group gathered in Cerisy-la-Salle for a meeting to discuss the work of Raymond Queneau. During this meeting, Queneau and François Le Lionnais planned the formation of the society.

In the years following its founding, Oulipo was not widely known as a group. As part of the Collège de 'Pataphysique, they shared their work with the full organization in 1961. In 1964, a French magazine called Temps Mêlés published an issue about Oulipo, and a Belgian radio station broadcast one of their meetings. Members worked individually during these years, creating and publishing works that followed specific rules. The group became more visible in 1973 with the publication of La Littérature Potentielle, a book containing examples of their work. In 1977, Martin Gardner introduced Oulipo to American readers in his Scientific American column. In 2012, Harvard University Press published a book about Oulipo called Many Subtle Channels: In Praise of Potential Literature, written by member Daniel Levin Becker.

Oulipo was founded by men in 1960. It took 15 years before the first woman joined; Michèle Métail became a member in 1975 but later left the group. From 1960 until now, only seven women have joined Oulipo. Clémentine Mélois joined in June 2017, and Louise Rose joined in 2026. Mélois left Oulipo in May 2026, stating that the group had difficulty including women as one reason for her departure. According to Oulipo’s rules, members cannot leave except in the case of death. To announce her departure, Mélois pretended to commit suicide at a café in Paris.

Members

The founding members of Oulipo included people who worked in different areas such as writing, teaching at universities, mathematics, engineering, and pataphysicians.
