In 1964 or 1965, Simonson discovered Marvel Comics, in particular that company's version of Thor. Simonson studied geology at Amherst College, with the intent of becoming an expert on dinosaurs.

Although Simonson was embarrassed to be seen by girls buying comics while in high school, he discovered Russ Manning's work on Magnus Robot Fighter right before he started college, and submitted a drawing that was printed in issue #10 in May, 1965, in the publication's fan page, 'Robot Gallery.' This was his first published work in comics. He also enjoyed drawing from a very young age. By the age of ten he was an avid fan of the work of Carl Barks, Little Lulu, Little Iodine, and Alex Toth's work on The Land Unknown. Simonson first read comics as a child, through the subscriptions to Walt Disney's Comics and Stories that his brother had. When his father, who worked for the United States Department of Agriculture, received a promotion at work that required him to relocate to Washington, D.C., Simonson, his younger brother and his parents moved to Maryland, where Simonson's parents still lived as of 1989. Walter Simonson was born September 2, 1946, in Knoxville, Tennessee, and lived there for two and a half years. He is married to comics writer Louise Simonson, with whom he collaborated as penciller on X-Factor from 1986 to 1989, and with whom he made a cameo appearance in the 2011 Thor feature film. Simonson has won numerous awards for his work and has influenced artists such as Arthur Adams and Todd McFarlane. He has also worked on other Marvel titles such as X-Factor and Fantastic Four, on DC Comics books including Detective Comics, Manhunter, Metal Men and Orion, and on licensed properties such as Star Wars, Alien, Battlestar Galactica and Robocop vs. He is also known for the creator-owned work Star Slammers, which he inaugurated in 1972 as a Rhode Island School of Design thesis.
