A BRIEF HISTORY OF ROBERT A. HEINLEIN

For science fiction fans, few names were as stellar as Robert A. Heinlein. From Starship Troopers to Stranger in a Strange Land, Heinlein was the dean of SF writers. Unfortunately, he rarely attended conventions, so his readers had few opportunities to meet the master in person.
Then in the early 1970s, Heinlein had a life-threatening illness and needed many pints of a rare blood type. He felt he owed his life to the donors, so when asked to be a guest at the 1976 Worldcon in his hometown of Kansas City, he agreed—but with one specific stipulation: that he would only sign autographs for people who donated blood.
Thus, longtime Comic-Con committee member Jackie Estrada approached the author with an offer to hold a blood drive in San Diego if he would consent to being a guest. He agreed, and in 1977 Heinlein came to Comic-Con. He and his wife, Ginny, had a great time and Heinlein even drew a picture for the Sunday morning Art Auction.tion.
“David Scroggy [who went on to be a VP at Dark Horse Comics before he retired] was the first blood drive coordinator,” recalls Estrada. “We also had Theodore Sturgeon there, signing his book, Some of Your Blood, which he gave to all of the blood donors. We also had entertainment for the people while they were [donating blood]. I remember that Leslie Cabarga played the piano, C. C. Beck played the guitar. It was a very fun event and Robert was delighted. We’ve had the blood drive every year since.”
