John Gall byl americký autor a pediatr, který proslul svou kritikou teorie systémů. Ve svých spisech se zabýval tím, jak systémy fungují, a zejména tím, proč selhávají, což vyústilo v definování tzv. Gallaova zákona. Jeho práce jsou ceněny pro pronikavý pohled na složitost a tendence systémů a nabízejí čtenářům nové úhly pohledu na pochopení světa kolem nás. Gallovy eseje zkoumají inherentní vlastnosti systémů a jejich nepředvídatelné chování.
