Osamu Tezuka
Tezuka began what was known as the manga revolution in Japan with his ''New Treasure Island'' published in 1947. His output would spawn some of the most influential, successful and well-received manga series including the children's manga ''Astro Boy'', ''Princess Knight'' and ''Kimba the White Lion'', and the adult-oriented series ''Black Jack'', ''Phoenix'' and ''Buddha'', all of which won several awards.
Tezuka died of stomach cancer in 1989. His death had an immediate impact on the Japanese public and other cartoonists. A museum was constructed in Takarazuka dedicated to his memory and life works, and Tezuka received many posthumous awards. Several animations were in production at the time of his death along with the final chapters of ''Phoenix'', which were never released. Provided by Wikipedia
