Alexander Milne Calder was a Scottish-born sculptor who came to Philadelphia and was given the commission for statuary for the City Hall.  He managed to squeeze in a monument for the Warner Family at Laurel Hill Cemetery that is probably the most photographed grave site on the property.  His son Alexander Stirling Calder is best remembered for Swann Fountain on Logan Circle, but he was also commissioned to do the statue for the grave of famed historian Henry Charles Lea, also at Laurel Hill.  The Calders are interred at West Laurel Hill under a large Celtic cross.
