AggieCon is the oldest and largest student-run multigenre convention in the United States. Held annually since 1969 by Cepheid Variable at Texas A&M University's Memorial Student Center, it has grown to become one of the larger conventions in Texas. AggieCon was the first science fiction convention ever sponsored by a college or a college affiliate student organization. Some former Cepheid Variable members have gone on to become science fiction/fantasy writers, including Martha Wells, Jayme Blaschke, and Steven Gould.
