Willy Ley Harrison's caption adds, "The remaining twenty-odd members showed up too late at the meeting." On April 29, 1984, Judith Merril, by then living in Toronto, founded a similar group for the burgeoning science-fiction community there, which she dubbed Hydra North. Author
Harlan Ellison discussed the Hydra Club and the inspiration for
L. Ron Hubbard's founding of Scientology in an interview with
Robin Williams. ==References==
