During the Gilded Age, Rittenhouse Square was home to Philadelphia's high society, with more millionaires per square foot than any other American neighborhood except New York's Fifth Avenue. Established by William Penn in 1682 as the South-West Square and renamed after astronomer David Rittenhouse in 1825, Rittenhouse Square and its environs changed from an isolated district of brickyards and workers' shanties into the city's most elegant and elite neighborhood between 1845 and 1865. The brownstone and marble mansions on the square itself were inhabited by the city's wealthiest and most prestigious families, with names like Biddle, Cassatt, Drexel, Stotesbury, and Van Rensselaer. As Philadelphia's upper classes fled to the suburbs in the early 20th century, their mansions were replaced by skyscrapers or taken over by cultural institutions like the Philadelphia Art Alliance and the Curtis Institute of Music. While only a few original residences remain on Rittenhouse Square, it is still the center of a lively upscale neighborhood.

Great cities and neighborhoods rise and fall, yet Rittenhouse Square in Philadelphia has seized the imagination and envy of social climbers, urban planners, and novelists alike for two centuries. In The Perfect Square, Nancy Heinzen—a resident of Rittenhouse Square for over 40 years and an activist committed to its preservation—provides the first full-length social history of this public urban space. One of the five squares William Penn established when he founded the city, the southwest-situated Rittenhouse Square has transformed from a marshy plot surrounded by brickyards and workers’ shanties into the epicenter of Philadelphia high society. A keystone of center city Philadelphia, it was once home to great dynasties, elegant mansions, and grand dames of the Victorian era. Today it is lined with million-dollar high-rise condominiums, where nouveau-riche entrepreneurs and descendants of ethnic immigrants live side-by-side. Heinzen lovingly chronicles this urban space’s development and growth, illustrating that not only is Rittenhouse Square unique, but so is the combination of human events and relationships that have created and sustained it. Painstakingly researched and generously illustrated with black-and-white photos from public archives, The Perfect Square will appeal to lay readers interested in history, to professional historians and urban planners, and to the thousands of new residents who have settled on or near Rittenhouse Square since the dawn of the 21st century.

The Benjamin Franklin Parkway has sliced through the Logan Square neighborhood of Center City (downtown) Philadelphia since World War I. Named after Philadelphia's favorite son, the mile-long boulevard begins at city hall and heads diagonally towards Logan Circle before reaching the Philadelphia Museum of Art. The postcards and other images in this work show the parkway's development and its role in Philadelphia's civic and cultural life. Despite often serving as a speedway into and out of town, the Ben Franklin Parkway is a triumph in urban planning that has become a treasured part of the City of Brotherly Love.
