Each year, Congregate remembers contributors that we have lost from the science fiction and fantasy world. The tradition began in memory of Aaron Allston, who was well known for his love of Hawaiian shirts.

We encourage everyone to wear a Hawaiian shirt on Friday of the convention, in honor of:​

• Alan Arkin
• Jamie Christopher
• John R. Douglas
• Ron Cephas Jones
• David McCallum
• Paul Ruebens
• Sydney J. Van Scyoc
