"[William] Anderson and his wife Claire, residents of Homestead, Fla., made a film called 'Monarch Butterfly Story' in their spare time. What was to have been the entry of two rank amateurs in an amateur movie club contest turned out to be an internationally acclaimed prize-winning educational film which was immediately purchased by Encyclopedia Britannica Films. The Andersons then accepted an offer to become producers of natural history subjects and have since researched, written the scripts, edited and sound-tracked 16 classroom films. They have also supplied sequences for three of Walt Disney's outstanding nature films." The Berkshire Eagle, Oct. 31, 1963, 9.
