The work of Walker & Gillette, one of the leading architectural firms of the twentieth century, is documented with an extensive text and over 800 illustrations. These include many unpublished works by the company and by architect Joseph Mordecai Hirschman, whose passion for old world buildings influenced their design. The first half of the twentieth century featured a wide variety of architectural styles, including Classicism, Art Deco, and Modernism, which Walker & Gillette used well. Established in the early twentieth century, this firm would remain active until the 1950s. Over the years, the firm diversified, planning residential country estates, urban mansions, town homes, and apartments. Commercial, corporate, and governmental architecture, Art Deco skyscrapers, and unique commissions are all covered, as are the interiors they created for private yachts, ocean liners, the Playland Amusement Park, and their 1939 New York World's Fair offering. This book has relevance and appeal to architects, artists, historians, and readers who love vibrant American history.
