Harrison’s first novel, Deathworld, was published in 1960, while the first book in the Stainless Steel Rat series was published a year later.
The last of the series was published just two years ago in 2010 and the books are widely regarded as producing one of science fiction’s great anti-heroes, Slippery Jim diGriz, aka The Stainless Steel Rat.
The author also parodied the sci-fi genre in his seven Bill the Galactic Hero books, which were first seen in 1965. He saw his work as anti-war and anti-militaristic.
