In that paper, I present my postdoctoral research on archives and gender. An important part of my project consists in collecting interviews with feminist activists to produce oral archives and online podcasts. I expose the general framework of this research (oral and women history), the purpose of the collect, the political and intellectual interests of producing archives and collecting life stories to understand gender-construction and support polyphony in feminism. I discuss important issues regarding knowledge and truth in oral archives and feminist research. I argue that a feminist and queer approach of gender as performative, grounded on a performative approach of language, can help us to analyze archives from an intersectional and non-essentialist perspective.
