Alexander Calder was a genius artist & one of the pioneers of Kinetic Art . He was a member of the Abstraction-Création creative collective in Paris & said to be a close friend of Joan Mirò.
Although he is most known for being the originator of the mobile (moving sculpture that is, not the phone) I first got to know him through his miniature Cirque Calder, which he created with found objects in the 1920’s while living in Paris.

The Cirque Calder is part of the permanent collection of the Whitney Museum in New York.
