September 1908. Gabriële Buffet, 27 years old woman, independent, musician, feminist before the hour, meets Francis Picabia, successful young painter and sulphurous reputation. He needed a renewal in his work, and was ready to break through the bonds: to breathe, to think, to theorize. She becomes "the woman with the erotic brain" who puts all men on their knees, including Marcel Duchamp and Guillaume Apollinaire. In Paris, New York, Berlin, Zürich, Barcelona, Étival and Saint-Tropez, Gabriële guides the precursors of abstract art, futurists and Dada, always at the forefront of artistic advances. This book takes us to the beginning of XX th century that reinvents the codes of beauty and society. Anne and Claire Berest are the great-granddaughters of Gabriële Buffet-Picabia--Translated by Stock.
