Aeschbacher was born in Geneva, Switzerland, in 1923, and studied at the Ecole des Beaux-Arts there, and at Fernand Leger’s Atelier in Paris.
His works have been included in group exhibitions a the Louvre (1964: “50 ans de collages”) and at the Pompidou (1985: “Lisible-Illisible”). His art may be found in museums in France, Belgium, Switzerland, China and Japan.
He began showing with the MADI artists in 1990, and is included in a catalog made that year. The Galerie Klaus Braun in Stuttgart currently carries his work.
