Metal has always been the material of choice for the most creative minds in the history of Art. Whether they are simple metals (iron, copper, tin, zinc, lead, aluminum, etc.), precious metals (gold, platinum, silver, etc.) or alloys (cast iron, steel, bronze, brass, etc.), all these raw materials have been manipulated as much by scientists as artists around the world. Mainly used for its malleability and resistance to the vagaries of time, metal has carved out a place of choice among the most renowned sculptors of our time. In 1912, Pablo Picasso experimented with metal and wire to create his iconic work, The Guitar. Jean Tinguely and Alexander Calder used metal to create sculptures full of movement and color. Jean Tinguely's companion, the famous Nikki de Saint-Phalle, used metal to solidify and perpetuate his sculptures of monumental women, Les Nanas. Elsewhere in France and in Europe, great artists will participate in the development of this material, in particular Alberto Giacometti and his threadlike characters, César and his compressions of objects, Louise Bourgeois and her impressive metallic spiders, or even Jeff Koons and his iconic Balloon Dogs.
