Since 1958 to 1961, Margery attended Carnegie Institute of Technology in Pittsburgh. In 1962 she got Bachelor of Arts degree, graduating from Wayne State University.
During the period from 1962 to 1965 Margery also attended Case Western Reserve University.
In 1962 Krueger started to work as a nuclear physicist at National Aeronautics and Space Administration (NASA) in Cleveland, a position she held until 1965.
Margery's first published story "Alienation" appeared in the science fiction magazine Analog in 1976, and she continued writing through the remainder of her life. She tried to inject a sense of fun into her writing. Regarded by some as a feminist writer, Krueger considered herself more as a "peoplist", dealing with such themes as bigotry and pollution in her fiction.
Since 1976 Margery served as a freelance writer.
Margery married Roger Carr Krueger in 1961. The couple gave birth to two daughters.
