Letchworth has unique distinction as the world's first Garden City, based on Ebenezer Howard's book Tomorrow: A Peaceful Path to Real Reform, published in 1898. Howard extended housing reform to encompass land purchase for the development of a complete town with housing, industry and open space. In 1899, the Garden City Association began the process of implementation, culminating in the purchase of the Letchworth Estate, unveiled in October 1903. The example of Letchworth has been studied worldwide and adopted in many countries, and Dr Miller's definitive new edition is published to celebrate Letchworth's centenary.
