1st World Science Fiction Convention

The 1st World Science Fiction Convention (Worldcon) was held on 2–4 July 1939 in the Caravan Hall in New York City, United States, in conjunction with the New York World's Fair, which was themed as "The World of Tomorrow". It was later retroactively named "NyCon I" by Forrest J Ackerman.

The convention was chaired by Sam Moskowitz. Along with Moskowitz, other organizers were James V. Taurasi, Sr. and Will Sykora.

Participants
Attendance was approximately 200.

Guests of Honor
The Guest of Honor at the first Worldcon was Frank R. Paul.

Other notable participants
Also attending were John W. Campbell, Isaac Asimov, L. Sprague de Camp, Ray Bradbury, Hannes Bok, Milton A. Rothman, John D. Clark, Jack Williamson, and Harry Harrison.

Controversy
In addition to its groundbreaking role as the first of its kind, the convention was noteworthy for the exclusion of a number of politicized Futurians by convention chair Sam Moskowitz; those excluded were Donald A. Wollheim, Frederik Pohl, John Michel, Robert A. W. Lowndes, Cyril M. Kornbluth, and Jack Gillespie, an event known to fannish historians as "The Great Exclusion Act."

According to Pohl, in his autobiography The Way the Future Was, the Futurians held their own counter-convention which was attended by several who went to the regular convention. He also downplayed the aspect that politics played, himself believing that it was a personality conflict between the convention organizers and the Futurians and said "We pretty nearly had it coming," continuing with "What we Futurians made very clear to the rest of New York fandom was that we thought we were better than they were. For some reason that annoyed them."

Programming and events
Ackerman and his girlfriend and fellow fanzine editor Myrtle R Douglas (Morojo) attended the convention in "futuristicostumes" designed and sewn by Douglas: this is considered a forerunner to modern fan costuming (which is known as "cosplay").

In 1994, the International Costumers' Guild (ICG) presented a special award to Ackerman recognizing him as the "Father of Convention Costuming" at Conadian, the 52nd Worldcon. In 2016, the ICG recognized Morojo as the “Mother of Convention Costuming” with a video award presentation at MidAmeriCon II, the 74th Worldcon.
