In 1948, Walter J. “Doc” Daugherty of the Los Angeles Science Fantasy Society proposed that an annual West Coast convention be started for West Coast fans who couldn’t afford to travel east each year. The first Westercon was held in September, 1948. It was a one-day event with an attendance of 77. It wasn’t until 1951 that the Westercon became a weekend-long event, settled into the July 4th holiday and began traveling to different cities. Note that according to Fancyclopedia 3, E. Everett Evans was the member of LASFS who introduced the motion to create Westercon and who chaired the first Westercon, with Daugherty chairing the second.

No Westercon was held in 2020 due to the COVID-19 pandemic. Westercons 73 and 74 were originally scheduled for July 2-5, 2020 and July 2-5, 2021 respectively, but postponed their conventions one year because of the restrictions on large group gatherings imposed by the pandemic conditions.

27. After initially being postponed for one year due to the COVID-19 pandemic, the convention announced on its Facebook page and web site on January 23, 2021 that it would be held entirely online/virtually and that there would be no in-person element to the convention. On April 11, 2021, the convention announced on its Facebook page and web site that the committee would not be able to hold the convention and that LASFS, owners of the Westercon service mark, would take over the official functions of Westercon and combine them with Loscon 47, November 26-28, 2021, at the Marriott Los Angeles Airport Hotel, under the provisions of the Westercon Bylaws.
28. These were the announced guests of Westercon 73 as originally planned in Seattle prior to the cancellation of the Seattle event. While the official functions of Westercon (Business Meeting and Site Selection) were assumed by Loscon 47, the guests of honor were not.
29. According to email from Registrar Jordan Brown dated 22 December 2021, “890 warm bodies, 245 no-shows.”
30. According to information from Registrar Linda Deneroff as of July 4, 2022 (updated July 23, 2022): 338 total members, 278 attending memberships sold, 1 child, 59 supporting, and 159 badges picked up.
31. No bids filed to host Westercon 75, and thus no qualified bid was selected through the ordingary site selection process at Westercon 73. The Westercon 73 Business Meeting awarded Westercon 75 to a committee consisting of Kevin Standlee and Lisa Hayes with the understanding that they would search for a different committee to actually operate the convention. On June 30, 2022 Standlee and Hayes announced that they had transferred Westercon 75 to a committee led by Arlene Busby and Michelle Weisblatt-Dane to hold the convention in Anaheim CA. On September 13, 2022, Weisblatt-Dane announced on Facebook that she was stepping down from co-chairing the convention for health reasons.
32. No bids filed with Westercon 73 by the April 15, 2022 deadline to appear on the 2024 Westercon site selection ballot. A write-in bid for Utah in 2024 filed with Westercon 73, but while the bid included a valid committee and site, it did not include a requisite non-profit organization. While 55 of the 60 votes cast (58 with preference) in the 2024 site selection election were for the Utah bid, it was not eligible to win the election and the decision was referred to the Business Meeting. Bids selected by the Business Meeting do not have to meet the conditions required to file bids for the normal site selection process. The Westercon 74 Business Meeting selected the Utah in 2024 bid committe to host Westercon 76, but strongly encouraged the committee to obtain non-profit status as the earliest opportunity.
33. On May 8, 2023, the Westercon 75 (Anaheim) committee announced that they would be unable to host the convention as originally planned. LASFS, owner of the Westercon service mark, took over the official functions of Westercon and combined them with Loscon 49, November 24-26, 2023, at the Marriott Los Angeles Airport Hotel, under the provisions of the Westercon Bylaws.
34. This was the announced guest of Westercon 75 as originally planned in Anaheim prior to the cancellation of the Anaheim event. While the official functions of Westercon (Business Meeting and Site Selection) were assumed by Loscon 49, the guests of honor were not.

36. No bids filed to host Westercon 77, and thus no qualified bid was selected through the ordingary site selection process at Westercon 75. The Westercon 75 Business Meeting awarded Westercon 77 to a committee consisting of Kevin Standlee and Lisa Hayes with the understanding that they would search for a different committee to actually operate the convention. On June 14, 2024, Standlee and Hayes announced that they had transferred Westercon 77 to a committee led by Sally Rose Robinson to hold the convention in Santa Clara CA in conjunction with BayCon 2025.
37. Combined with BayCon 2026.
