Sandy's own father, Alexander Sterling Calder, created many beautiful public monuments across the United States including Swann Memorial Fountain in Philadelphia. As a child Sandy was very interested in sculpture. When Sandy was a young man he decided he wanted to be an Engineer and received a degree in Engineering at Stevens Institute of Technology in Hoboken, New Jersey.

Calder received his arts education from the Art's Students League in New York and the Académie de la Grande Chaumière in Paris. He created the Mobile structure and received acclaim for his bold abstract work. Calder would eventually create many important giant public monuments. The piece above was created in 1945. Calder passed away of a heart attack in New York in 1976.
