Walter "Walt" Simonson (born September 2, 1946) is an American comic book writer and artist. After studying geology at Amherst College, he transferred to the Rhode Island School of Design, graduating in 1972. His thesis project there was The Star Slammers, which was published as a black and white promotional comic book for the 1974 World Science Fiction Convention in Washington, D.C. (DisCon II). In 1983, he produced another version of the story in graphic novel form for Marvel Comics. Simonson continued the adventures of the Star Slammers in a limited series in the mid-1990s as one of the founders of Malibu Comics' short-lived Bravura label. Simonson has won numerous awards for his work, and has influenced artists such as Arthur Adams and Bryan Hitch.
