Osamu Tezuka was a Japanese manga artist, cartoonist, and animator whose revolutionary comics earned him the title of manga no kamisama ("God of Manga"). His body of work is one of the largest and most prolific in all of Japanese culture, and he produced several of the country's greatest drawn stories for both children and adults, including the iconic Astro Boy, Kimba the White Lion, Black Jack, Dororo, Message to Adolf, and Princess Knight. Tezuka passed away in 1989.
