This is the inaugural volume of a planned seven-volume catalogue raisonne on the Spanish sculptor Julio Gonzalez (1876 1942). The son of a goldsmith in Barcelona, Gonzalez studied painting and sculpture from an early age. Upon moving to Paris in 1900, he joined the company of fellow Spanish artists such as Juan Gris, Pablo Gargallo and Pablo Picasso. Today, Gonzalez is primarily known for his work in welded iron. Abstracted figures such his Monsieur’ Cactus (1939) show a connection to the Cubist sculptures of Picasso, with whom Gonzalez worked closely from the 1920s onward. Credited with introducing Picasso to welded sculpture, Gonzalez was also an important influence on the American Abstract Expressionist sculptor David Smith. This monumental project is published in collaboration with the Instituto Valenciano de Arte Moderno in Spain, which possesses the largest collection of Gonzalez’s work.
