Catherine Deudon, herself a "historic feminist" (as the French call the pioneers), has been photographing the French women's liberation movement since its inception.  You can read an interview, in French, about her involvement in the movement and about her photography.  Deudon describes her itinerary as follows:

I fell into the developer*, the stop bath (even more acidic than I) and the fixer at about age 16.  I read Simone de Beavoir at 17, and encountered May '68 at 28.  Everything else came naturally: putting together photography and Simone de Beauvoir, and, at 30, encountering the women's liberation movement.  And I've been at it every since: over 36 years of activism and far more images.
[*In French, the chemical solution is called a révélateur, i.e. the same root as revelation]

Deudon has generously donated several images of relevance to the American movement.  Please do not reproduce or use them without obtaining permission.  To contact her, click here.

Deudon has recently published a collection of some 200 of these photographs, the only book of its kind:
"Un mouvement à soi, 1970-2001, livre de photographies" (Paris: Syllepse, 2003);
