the Paris International Exposition of 1900. They won two prizes for their window entitled "Religion Enthroned" designed by Frederick Stymetz Lamb (1862–1928), the third of Joseph's sons. Frederick's brother, Charles Rollinson Lamb (1860-1942), a renowned City Beautiful theorist and architect, shaped the studio's aesthetic and intellectual character and business. Frederick became its head of design and supervised the firm's team of skilled craftsman. In the early 1920s Frederick and his wife Nellie moved to Berkeley, California where he supervised local civic projects and frequently exhibited his landscapes in oil to great acclaim at the art colonies in Berkeley and Carmel-by-the-Sea, California.
