Gustavo Bar Valenzuela is a Chilean-born painter who has been residing in Israel since 2005. He studied painting at Academia Arte Real in Chile, under the guidance of founder Ricardo Ramírez. There he mastered compositional and structural drawing, and painting techniques ranging from the Pre-Raphaelites to Flemish Art. Later he became the first director of the school's branch at La Serena. In addition, Bar Valenzuela received his BA in Art History and Restoration from SEK International University of Chile.

With the traditions of European painting in mind, Bar Valenzuela combines aesthetic influences from the Flemish and the Venetian schools with the technique of the Baroque era. In this manner he creates a fresh and revisited realism, rooted in the updated traditions of the old masters. His recent paintings have a strong contemporary feel and they depict modern-day subjects and sceneries in a distinct figurative style.

Works by Gustavo Bar Valenzuela have been exhibited in solo and collective exhibitions in Chile, Israel, Italy and the US.
