Alfred Lammer (1909–2000) was an Austrian-born British photographer, educator, and designer. He is recognized primarily for his technical contributions to architectural photography and his documentation of medieval English stained glass.
Born in Linz, Austria, Lammer emigrated to the United Kingdom in the 1930s. During the Second World War, he served as a navigator in the Royal Air Force (RAF), where he was awarded the Distinguished Flying Cross. His wartime service and interest in aviation led to a lifelong involvement in gliding; he eventually authored works and instructional materials regarding the technical aspects of the sport.
Following the war, Lammer developed a career in professional photography and design. He became a senior lecturer at the Central School of Arts and Crafts (now known as Central Saint Martins) in London, where he taught photography and influenced the development of glass design curricula.
Lammer is most noted for his specialized photography of ecclesiastical art. His work on the 13th-century stained glass at Canterbury Cathedral is considered a significant record of the medium. His photographs were utilized in major publications, most notably English Stained Glass (1960), which featured his imagery alongside text by John Baker. This work was praised for its objective and detailed reproduction of color and leadwork, which was technically challenging given the lighting conditions of medieval cathedrals.
His photographic works are held in several major institutional collections, including the Victoria and Albert Museum and the National Portrait Gallery in London. Lammer died in 2000.
