Jean Arp (1886-1966) was born in Strasbourg, first under German citizenship, and later under French citizenship. He was a poet, a friend of Paul Éluard, and in 1916, the co-founder of the Dada group. This group borrowed the word dada, which means hobby horse, from the vocabulary of young children, in order to make fun of “serious” art and literature. His sculptures, which became more and more abstract, brought him international fame.
