Born in 1898 in Philadelphia, died in New York in 1976 (United States)
Alexander Calder made his first pieces of jewelry at the age of 8 for his sister's dolls.
In 1928, he returned to the subject of jewelry, handcrafting more than 1,800 pieces throughout his life.
In 1942, he gave a necklace to Chagall's wife; he placed a piece of broken porcelain in a copper bracelet for Miró, his lifelong friend.
He spoiled Teeny Duchamp and Peggy Guggenheim.
For his wife, Louisa, he made a "Medusa" bracelet in homage to her very curly hair; for his daughter, a pendant around her baby tooth.
He sold only a few pieces of jewelry during the war, but never produced for commercial purposes.
