Peter Sagal is best known as the host of National Public Radio's irreverent weekly news quiz "Wait, Wait ... Don't Tell Me." He has often identified himself on the radio as a science fiction fan, and was expected to impart an additional dose of Chicago into Chicon 7 with his knowledge and humor.
Sagal's commitment to filming a new documentary unfortunately requires him to be overseas during the weekend of Chicon 7, making it impossible to participate in the event. Sagal has expressed his apologies to the Chicon 7 team, saying "I'm heartbroken I won't be able to attend my first Worldcon since 1980. As it happens, I'll be in ReykjavÌk, or some other place less interesting than Chicago. I wish everybody all the best."
Chicon 7 is the 2012 World Science Fiction Convention. The first Worldcon occurred in New York City in 1939 and Worldcons have been held annually since then except for 1942-45 when there was no event due to World War II. Chicon 7's Guests of Honor are five-time Hugo winning author Mike Resnick, artist Rowena Morrill, art agent and collector Jane Frank, science fiction fan and former Worldcon chair Peggy Rae Sapienza, and astronaut Story Musgrave. Chicon 7's Toastmaster is John Scalzi.
