This is the indispensable bible of photography in the 20th century. The history of photography began over a century & a half ago but only relatively recently has it been fully recognised as a medium in its own right. Cologne's Museum Ludwig was the first museum of contemporary art to devote a substantial section to international photography. The L. Fritz Gruber collection from which this book is drawn is one of the most important in Germany & one of the most representative anywhere in the world constituting the core of the museum's holdings. This book provides a fascinating insight into the collection's rich diversity; from conceptual art to abstraction to reportage all of the major movements & genres are represented via a vast selection of the century's most remarkable photographs. From Ansel Adams to Piet Zwart over 850 works are presented in alphabetical order by photographer with descriptive texts & photographers' biographical details providing a comprehensive & indispensable overview of 20th century photography.
