The Combinatorial Potlatch is an international one-day conference, usually held on the Saturday preceding US Thanksgiving. It has been held for many years at various locations around Puget Sound and southern British Columbia, and is an opportunity for combinatorialists in the region to gather informally for a day of invited talks and conversation. While most who attend work in, or near, the Puget Sound basin, all are welcome. Typically there are three talks given by speakers who are visiting or new to the area, along with breaks for coffee and lunch. Many participants remain for dinner at a local restaurant or pub.

The American Heritage Dictionary defines "potlatch" as: A ceremonial feast among certain Native American peoples of the northwest Pacific coast, as in celebration of a marriage or an accession, at which the host distributes gifts according to each guest's rank or status. Between rival groups the potlatch could involve extravagant or competitive giving and destruction by the host of valued items as a display of superior wealth. [Chinook Jargon, from Nootka p'achitl, to make a potlatch gift.]

History of the Potlatch

The first Potlatch that anyone can recall was held in 1982 at the University of Washington (though Pavol Hell insists there were meetings in the 70's). From that time, through 1997, Brian Alspach was the prime mover and organizer. After a few years' hiatus, Nancy Neudauer and Rob Beezer resurrected the tradition in 2002. There have been at least 31 meetings over the past 32 years. A history, as best as can be reconstructed, is available in HTML and PDF formats.
