It all starts with a photograph and a family story. During a dinner, Hannah Assouline meets Jean Besancenot and discovers his photographs. Between 1934 and 1937, he immortalized a vanished world by drawing and photographing the Jewish rural populations of Morocco. In one of the prints, she recognizes her father's face. Photo by photo, the story of her family and her origins is written in this remarkable work. In the exhibition Jews of Morocco at the Museum of Art and History of Judaism, it is her turn to retrace the genesis of Besancenot's work. Exploring the southern regions of Morocco, this self-taught ethnographer is particularly interested in the clothing and jewelry that people wear during celebrations. Impressive headdresses, heavy jewelry, sumptuous fabrics... He photographs out of necessity, to be able to meticulously transcribe the details in his gouaches. The result is a formidable heritage inventory, with a corpus of nearly 1800 images. Today, the MahJ gives us the unique opportunity to discover this unknown photographer whose work is collected through public and personal collections. A real adventure to be lived in the heart of a bygone era and vanished traditions!
