Osamu Tezuka was a Japanese cartoonist, animator, film producer, and activist. Born in Osaka Prefecture, he is best known as the creator of the comics series Astro Boy, Kimba the White Lion and Black Jack. His prolific output, pioneering techniques, and innovative redefinitions of genres earned him such titles as the father of manga, the god of comics, and kamisama of manga. Additionally, he is often credited as the godfather of anime and is considered the Japanese equivalent to Walt Disney, who served as a major inspiration during Tezuka's formative years.
