Today 03 November is Day of Manga, because the birthday of Osamu Tezuka (1928-1989)

An excerpt from tezukaosamu.net-

Tezuka Osamu's manga and animated films had a tremendous impact on the shaping of the psychology of Japan's postwar youth. His work changed the concept of the Japanese cartoon, transforming it into an irresistible art form and incorporating a variety of new styles in creating the "story cartoon." Changing the face of literature and movies, his work also influenced a range of other genres.
His impact on animated film was equal to that which he had on the manga world. The lovable characters appearing in works such as Japan's first animated TV series "ASTRO BOY," the color animated TV series "Jungle Emperor Leo", and the two-hour animated special "Bander Book," captured the hearts of the Japanese through the medium of television, propelling the animated film to tremendous popularity in Japanese general society.
