How did a young artist at the beginning of the 20th century, rejected by the Academy of Fine Arts in Germany because she was a woman, always seen in the shadow of her companion, Vassily Kandinsky, become an eminent painter in an unprecedented artistic movement? With the support of several contributors and personal writings, Gabriele Münter - Pionnière de l'art moderne, retraces the life of one of the most illustrious figures of the German expressionist movement of the Blue Rider and draws up the portrait of a singular artist, whose work, intimate and human, testifies to the complexity of her time as much as that of her own existence.
