Thanks to its expertise, the museum is also internationally recognized for its skills in managing complete photographic collections, which is why it has been entrusted with collections from the studios of Jongh, Pierre Gilliard, Gertrude Fehr, Ella Maillart, Rodolphe Schlemmer, Nicolas Bouvier, Charles Chaplin, Maurice Blanc, Jules Jacot-Guillarmod, Jean Herbert, Edouard Payot, Marcel Imsand, Jean Mohr, Hans Steiner, Jean-Pierre Grisel, Maurice Vouga, Suzi Pilet, Jan Groover, Lehnert & Landrock, Olivier Föllmi, René Burri, Pierre Keller and Sabine Weiss.
The notion of archives is particularly decisive, making it possible to trace the modus operandi of a given photographer through their negatives, contact sheets, proofs, exhibition prints, notebooks, correspondence, account books, paper documentation, publications and digital files. Conserving complete collections enables us to understand how each photographer considered their craft and developed their creative process or modus operandi, their professional career and their relationship with the medium, as well as their projects over the years.
