Short answers, pulled from the story.
Osamu Tezuka died on the 9th of February 1989 of stomach cancer after being rushed to a hospital in Tokyo. His last words were "I'm begging you, let me work!", spoken to a nurse who tried to take away his drawing equipment.
Tezuka's first professional work was Diary of Ma-chan, serialized in the elementary school children's newspaper Shokokumin Shinbun in early 1946. He was 17 years old at the time.
Tezuka cut production costs to 2.5 million yen per episode using techniques including shooting on threes, stop images, repetition, sectioning, and short shots. These methods, refined at his studio Mushi Productions, were subsequently adopted across the television anime industry.
In January 1965, Tezuka received a letter from Stanley Kubrick inviting him to serve as art director on 2001: A Space Odyssey. Tezuka was flattered but declined because his schedule would not allow him to live in England for a year.
Tezuka considered Phoenix his life's work. He began the series in 1954 and continued it until his death, though it remained unfinished. In a 2006 Japan Media Arts Festival poll, Phoenix ranked first among the greatest manga of all time.
The Osamu Tezuka Manga Museum is located in Takarazuka, where Tezuka grew up, and was inaugurated on the 25th of April 1994. It holds a manga library with five hundred of his works, a video library, an Animation Workshop, and a glass sculpture based on a book he wrote in childhood called Our Earth of Glass.
