American design legend Albert Hadley's passed away this past March. Here we're honouring his work with spaces from his 2005 book, Albert Hadley: The Story of America's Preeminent Interior Designer (Rizzoli). Based on interviews with Hadley, biographer Adam Lewis does a great job of capturing the celebrated designer's style. The book features a roundup of his interior design projects that spans 50 years, and traces the path of a career that brought Hadley into contact with major figures in 20th century design, from Billy Baldwin to Van Day Truex and Eleanor Brown. Here, browse photos of rooms that made design history, from the magnificent Gracie Mansion in New York City to Mrs. Vincent Astor's ruby red library.
