Astro Boy of Tezuka Osamu
Dr. Osamu Tezuka (1928-1989) was a Mangaka (Japanese Manga artist) and animator. Born in Osaka Prefecture, he is best known as the creator of Astro Boy and Kimba the White Lion. He is often credited as the Father of Anime, and is considered by some to be the Japanese equivalent to Walt Disney.
Famous creations of his include Astro Boy (Tetsuwan Atomu in Japan), Black Jack, Princess Knight (the first shojo, or girls-oriented, manga/anime series), Phoenix (Hi no Tori in Japan), Kimba the White Lion (an uncredited inspiration for Disney's The Lion King), and Adolf.
His "life's work" was Phoenix—a story of life and death, concerning an eponymous phoenix whose blood endows those who drink it with immortality.
