In 1912, German art collector Wilhelm Uhde, the first buyer of Picasso and the discoverer of the customs officer Rousseau, rented an apartment in Senlis to write and take a break from his Parisian life. He hired a cleaning woman, Séraphine, 48 years old. Some time later, he noticed a small painting on wood among the belongings of local notables. His astonishment was great when he learned that the artist was none other than Séraphine. Thus began a poignant and unexpected relationship between the avant-garde art dealer and the visionary cleaning woman.
