The professional Guest of Honor at the 34th Worldcon was former Kansas Citian Robert A. Heinlein. He did not prepare a formal guest of honor speech, as such, but gave a generally well received one, immediately following the convention's Hugo Awards ceremony at the nearby Art Deco-inspired Music Hall section of the Kansas City Municipal Auditorium. Heinlein came with an alarm clock and put it on his center stage podium and spoke casually until his own preset time period ended with the alarm going off. Heinlein was previously the Guest of Honor at the 3rd Worldcon (1941) and the 19th Worldcon (1961). He remains the only science fiction writer honored three times by the annual World Science Fiction Convention. Heinlein attended many MidAmeriCon events, including a blood donation drive and later donor reception held at the nearby Hotel Continental, one of the Worldcon's overflow hotels. Being someone with a very rare blood type, Heinlein had organized the blood drive and reception to honor those anonymous donors who had donated blood, saving lives during surgeries, including his own earlier in the decade.
