He gave Philadelphia its skyline silhouette by sculpting the massive statue of William Penn that crowns City Hall.
Alexander Milne Calder arrived in Philadelphia from Scotland in 1868, a young sculptor stepping into a city about to erect its grandest civic building. For three decades, his chisel was central to the creation of Philadelphia City Hall, an epic project that became his life's work. He oversaw a small army of carvers, producing more than 250 pieces of architectural sculpture that adorn the building's granite façade. His most enduring legacy is the 37-foot-tall, 27-ton statue of William Penn, which he modeled in his studio and saw hoisted to the tower's peak in 1894. This figure, clad in colonial dress, became the city's visual anchor and a symbol of its ambitions. Calder established a creative dynasty; his son, Alexander Stirling Calder, became a major sculptor of public monuments, and his grandson was the kinetic art pioneer Alexander Calder.

His grandson, Alexander Calder, initially trained as a mechanical engineer before turning to art.
The statue of Penn was raised to the tower in sections using a wooden derrick.
Calder's original plaster model for the Penn statue is housed at the Pennsylvania Academy of the Fine Arts.
