Margaret Edith Weis (born March 16, 1948) is a fantasy and science fiction writer and author of dozens of novels and short stories. Along with Tracy Hickman, Weis is one of the original creators of the Dragonlance game world.
Margaret Weis was born on March 16, 1948, in Independence, Missouri. She discovered heroic fantasy fiction while studying at the University of Missouri (MU). "I read Tolkien when it made its first big sweep in the colleges back in 1966," she said. "A girlfriend of mine gave me copy of the books while I was in summer school at MU. I literally couldn't put them down! I never found any other fantasy I liked, and just never read any fantasy after Tolkien."
Weis graduated from MU in 1970 with a bachelor's degree in creative writing and literature.
Weis first worked for a small publishing company in Independence, where she became an editor. From 1972 to 1983 she worked for Herald Publishing House as advertising director and subsequently as director of Independence Press, Herald Publishing's trade division from 1981 to 1983.
