Randy Reichardt sends word that Chester D Cuthbert passed away in Winnipeg on Friday, March 20, 2009:
Chester was a member of First Fandom, and had two stories published by Hugo Gernsback in the February and July 1934 issues of Wonder Stories. Chester was good friends with Sam Moskowitz and Forry Ackerman, both of whom visited him at his home during the Worldcon in Winnipeg in 1994. He was an intergral part of the Canadian sf scene for decades.
My university, the University of Alberta, accepted his amazing collection on donation in the fall of 2007, and the donation received international news coverage at the time.
Update 03/24/2009: A detailed obituary about Cuthbert plus a photo is posted here.
