Xavier Valls was a Spanish painter born in 1923 in Horta. He learned to paint with the Swiss sculptor Charles Collet who also taught him the modeling of various materials as well as the discovery of artists such as Cézanne, Matisse, and Picasso. In 1939 he studied at the Massana school then worked as a creator at the jeweler Ramon Sunyer Clarà. In 1946 he founded the Cercle Maillol with Suzanne Alemany, Charles Collet, Alfred Figueras and Bernard Sanjuan to organize exhibitions.
Valls received a grant in 1949 from the French Institute of Barcelona to go to Paris in Montparnasse. There he met other artists such as Antoni Clavé, Joaquin Peinado and Javier Vilató. He collaborated with Fernand Léger during 4 years on the realisation of the stained glass of the Audincourt church. The artist presented still lives and landscapes at the autumn Salon in 1953. Valls captures the everyday, the emotion, and the intimacy of a lived experience. His practice is composed of still lives, landscapes and portraits.

Retrospectives on his work are organized in France and Spain in the 80s.
