André Ferdinand Fossum (* 22.8.1899 in Vardø, † 16.1.1986) Norwegian composer and International Master. "André Fossum was one of the greatest non-Czech specialists in the world for Bohemian problems. He composed almost 200 Bohemian threemovers and became International Master for Chess Composition in 1980. He commented his own problems in "Sjakkoppgaver og studier" (1975). He also composed studies. One of his studies is commented in Norwegian by Jarl H. Ulrichsen in his article published in Sjakkhuset: "Norsk Studiekavalkade1" (pg. 10-11)."
