Josef Müller (born 15 February 1887 in Solothurn; died 24 March 1977) was a Swiss art collector and curator.
He became a student of Cuno Amiet and set up his own studio, initially in Geneva, and from 1922 in Paris.
Like his sister Gertrud Dübi-Müller, Müller maintained contacts with the most important Swiss artists of his time at a young age, such as Ferdinand Hodler,[2] Cuno Amiet, Giovanni Giacometti, and Félix Vallotton.
He acquired their works as well as those by Pablo Picasso, Paul Cézanne, Fernand Léger, Henri Matisse, and others.
The pre-Columbian art part has been shown in Barcelona since 1997 and was auctioned at Sotheby's in 2013, as neither the municipality nor the Spanish state could raise the funds for a purchase.
