Osamu Tezuka (3 November 1928 - 9 February 1989) was a Japanese manga artist, cartoonist and animator. Considered to be among the greatest and most influential cartoonists of all time, his prolific output, pioneering techniques and innovative redefinitions of genres earned him such titles as "the Father of Manga", "the Godfather of Manga" and "the god of Manga". Additionally, he is often considered the Japanese equivalent to Walt Disney, who served as a major inspiration during Tezuka's formative years. Though this phrase praises the quality of his early manga works for children and animations, it also blurs the significant influence of his later, more literary, gekiga works.
