Harry Harrison was born in 1925 and was drafted into the army on his eighteenth birthday. His experiences during World War II left him with a hatred of all things military, demonstrated in his satirical novel Bill, the Galactic Hero. Many of his early stories appeared in John W. Campbell's Astounding, often reflecting his interest in environmental issues and non-violent resolutions to conflict. His best-known creations are The Stainless Steel Rat and Make Room! Make Room! on which the film Soylent Green was based. More recent works include best-selling alternate world trilogies West of Eden and Stars and Stripes Forever!
