Joan Miró
Joan Miró was already a highly acclaimed artist when he discovered a painting by the young François Fiedler in a corner shop in Paris. His fascination with Fiedler's work led to an introduction to Aimé Maeght and a lifetime friendship, and the two often shared studio space at the Fondation Maeght.
Fiedler and Miró's works have been featured in 13 joint exhibitions as of this date according to the Fiedler Foundation website.
