Oulipo founded (24/11/1960)

OUvroir de LIttératire POtentielle (Workshop of Potential Literature)
"a group of mainly French writers who created experimental works using techniques of constrained writing"
Examples of constraints:
- using only words extracted from a previously existing text [as in _A Humument_]

- a technological length constraint [Twitterature]
- avoidance -- writing a work that does not contain a particular letter (lipogram) or punctuation mark or part of speech
_Gadsby_ by Ernest Wright, uses no <e>

_La Disparition_ by Georges Perec likewise
(Perec is the only one of the Oulipo group Crystal names)
- or insistence -- every word must contain a particular letter...etc.

I guess the -lipo in Oulipo was probably a deliberate link to the lipo- in lipogram (which goes back to the 18th century), from Greek leipein 'to leave out, to be missing'.
"Ouvroir" is a pretty obscure word. (A "writer's workshop" would, I think, normally be called an "atelier" in French.) Petit Larousse says
Ouvroir (n.m.) Etablissement de bienfaisance où des jeunes filles et des femmes se livrent en commun à des travaux de lingerie; dans les communautés de femmes, lieu où les religieuses s'assemblent pour travailler.
Sounds a bit like the Magdalen Laundries, or a workhouse for indigent females.
Any special reason why they would choose that? (All those named in the Wiki article were men. They did, however, have some connection with Pataphysics -- which we won't get into here.)
