The sensuously undulant lines of Bruno Mathsson's furniture designs made him one of the leading figures of Swedish modernism in the 1930s. Chairs that adapted to their occupant, contoured to follow the human form with graceful natural curves and made from laminated wood and canvas webbing became his trademark and have been in continuous production for more than fifty years. Mathsson (1907-1988) is internationally known as a furniture designer but his architectural work, in which he applied the same principles of innovative comfortable living, is less familiar. His family houses, schools, nurseries, factory buildings and exhibition halls are light and airy constructions with large glazed sections, built in a rational modular system. Throughout his work, the connections between design and ergonomics, aesthetics and innovative materials, energy saving and environmental concerns resonate for designers today. Mathsson's output as an architect and designer, unpublished photographs of his work in situ, and his relationships with American architects and designers including Frank Lloyd-Wright, Charles and Ray Eames, and Hans Knoll are surveyed in this book, published to coincide with an exhibition organized by the Architecture Museum, Stockholm, and travelling to Paris, New York and Washington.
