Alexander Milne Calder

Career In 1872, he was hired by architect John McArthur Jr., to produce models for the sculptures adorning Philadelphia City Hall. The commission required more than 250 marble and bronze pieces over the 30 year construction. That same year, Calder was commissioned by the forerunner of Philadelphia's current Association for Public Art, the Fairmount Park Art Association, to create an equestrian statue of Major General George Gordon Meade which was installed in 1887.

In 1875, he won the competition to create the bronze statue of William Penn for the new City Hall. In 1877, Calder used one of the offices in city hall as his studio and worked there through the construction period. The statue is 37 feet tall, and weighs over 53,000 pounds. Calder originally made a clay model nine-feet tall and kept enlarging it until it reached 37 feet tall. The sculpture sat unfinished for 2 years until the Tacony Iron and Metal Works opened in 1889 with the capacity to cast the statue. The statue was cast in 1892 Calder was frustrated that the statue was installed facing northeast toward Penn Treaty Park rather than south as he wanted. This positioning results in the statue face being in shadow except in early morning light. Philadelphia City Hall also contains 250 relief and free-standing statues from Calder and his assistant James G. C. Hamilton.

Calder died on June 4, 1923,

Legacy A historical plaque at Philadelphia City Hall highlights Calder's work on the building. His son, Alexander Stirling Calder, and grandson Alexander Calder were also sculptors.
