Today is the birthday of Grand Master and sf icon Harry Harrison. He's a giant in the field and the author of classics like the military sf parody, Bill, the Galactic Hero (1965), and the socially relevant, Make Room! Make Room! (1966), which was the basis of the film Soylent Green (1973).
He also wrote The Deathworld Trilogy (1974), and perhaps his most famous series telling the tale of Slippery Jim DiGriz, The Stainless Steel Rat (1960 onward).
Happy birthday Harry, and many more.
