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.

Letting Go? investigates path-breaking public history practices at a time when the traditional expertise of museums seems challenged at every turn—by the Web and digital media, by community-based programming, by new trends in oral history and by contemporary art. In this anthology of 19 thought pieces, case studies, conversations and commissioned art, almost 30 leading practitioners such as Michael Frisch, Jack Tchen, Liz Ševcenko, Kathleen McLean, Nina Simon, Otabenga Jones and Associates, and Fred Wilson explore the implications of letting audiences create, not just receive, historical content. Drawing on examples from history, art, and science museums, Letting Go? offers concrete examples and models that will spark innovative work at institutions of all sizes and budgets. This engaging new collection will serve as an introductory text for those newly grappling with a changing field and, for those already pursuing the goal of “letting go,” a tool for taking stock and pushing ahead.

Since the 1960s, public attention has been drawn increasingly towards the thematic link between historic preservation and urban planning. Nowadays, the organized historic preservation movement in the USA is more than a mere "yearning for history": it represents an active and integral part of urban planning in US cities. In order to approach these planning, economic, and social issues in the field of historic preservation, this book analyzes a variety of interdisciplinary methods, focusing on four selected historic districts within the central business districts of Philadelphia and Boston (in the north) and Charleston and Savannah (in the south).
