Hugo Award
The World Science Fiction Society (WSFS) gives out the Hugo Awards each year for the best science fiction or fantasy works and achievements of the previous year. The award is named after Hugo Gernsback, who founded the pioneering science fiction magazine "Amazing Stories" and who is considered one of the "fathers" of the science fiction genre. Works are eligible for an award if they were published in the prior calendar year, or translated into English in the prior calendar year. There are no written rules as to which works qualify as science fiction or fantasy, and the decision of eligibility in that regard is left up to the voters, rather than to the organizing committee. Hugo Award nominees and winners are chosen by supporting or attending members of the annual World Science Fiction Convention, or Worldcon, and the presentation evening constitutes its central event. The selection process is defined in the WSFS constitution as instant-runoff voting with five nominees per category, except in the case of a tie. The awards are split over more than a dozen categories, and include both written and dramatic works.
Hugo Award for Best Novella
Beginning with the 1996 Worldcon, the World Science Fiction Society created the concept of "Retro Hugos", in which the Hugo award could be retroactively awarded for years 50, 75, or 100 years before the current year, if no awards were originally given that year. Retro Hugos have been awarded six times, for 1939, 1941, 1943, 1946, 1951, and 1954. The 1939, 1941, and 1943 Retro Hugos were awarded 75 years later, the other three were given 50 years later.
