STIRLING CALDER [sic] who was named acting chief (under Karl Bitter) of the sculpture program for the Exposition. He completed three large sculpture groups for the event, The Nations of the East, The Nations of the West, and The Fountain of Energy. Along with Hermon MacNeil, designer of the Standing Liberty quarter, he was commissioned to do sculptures for the Washington Square Monument in New York. Each artist accomplished a large work for the Monument, and Calders, Washington as President, is one of his most notable works. Both his father and son were also accomplished sculptors. His father, Alexander Milne Calder, did considerable work on Philadelphia City Hall, including the 37-foot sculpture of William Penn that tops its central tower. His son, also named Alexander, is the most famous of the three artists for his colorful mid-century mobiles, monumental sculptures and other works.；
