Architect David Adler (1882-1949), who shunned publicity, was hired by some of America’s leading entrepreneurs during the Great House Era, which includes the bygone time as such in the Great Gatsby. Most of his Classical home designs, over 45 in all, are on a grand scale, still stand and are cherished by owners. At least 12 are on the National Register of Historic Places. Showcasing rare architectural footage of exteriors and interiors, this four-part series features interviews at four Adler designed homes.
