Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.
Conventional wisdom credits only entrepreneurs with the vision to create America's commercial airline industry and contends that it was not until Roosevelt's Civil Aeronautics Act of 1938 that federal airline regulation began. In Airlines and Air Mail, F. Robert van der Linden persuasively argues that Progressive republican policies of Herbert Hoover actually fostered the growth of American commercial aviation. Air mail contracts provided a critical indirect subsidy and a solid financial foundation for this nascent industry. Postmaster General Walter F. Brown used these contracts as a carrot and a stick to ensure that the industry developed in the public interest while guaranteeing the survival of the pioneering companies. Bureaucrats, entrepreneurs, and politicians of all stripes are thoughtfully portrayed in this thorough chronicle of one of America's most resounding successes, the commercial aviation industry.
