In 1940, Adams created "A Pageant of Photography", the largest and most important photography show in the West to date, attended by millions of visitors. With his wife, Adams completed a children's book and the very successful "Illustrated Guide to Yosemite Valley" during 1940 and 1941. He also taught photography by giving workshops in Detroit. Adams also began his first serious stint of teaching, which included the training of military photographers, in 1941 at the Art Center School of Los Angeles, now known as the Art Center College of Design.
