Book excerpt: This book covers the 20 years that transformed Philadelphia into a city of neighborhoods, from Kingsessing to Wissahickon. At the turn of the 20th century, Philadelphia was the "workshop of the world," with builders toiling tirelessly to fill the staggering demand for housing. This golden age of construction resulted in whole new neighborhoods for the city's burgeoning population, transforming it into a place where immigrants could easily find jobs and a community to call their own. More than 200 vintage photos and postcards whisk readers back to the neighborhoods as they once were, exactly as our grandparents and great-grandparents knew them, before modern influences altered them beyond recognition. Arranged by neighborhood, this Philadelphia family album, a scrapbook for the city, is filled with rare vintage photographs and comprehensive information about the houses, the builders, the neighborhoods, and the people who lived in them.
