According to Sam Moskowitz, "It was suggested by John B. Michel that the club [the NYB-ISA] plan a social outing of some sort; this was agreed to, great controversy ensued as to the destination. Philadelphia was decided upon, chiefly because Wollheim had hit upon the novel idea of meeting with out-of-town fans and thereby calling the affair a science fiction convention."
On October 22, 1936, the NYB-ISA (including Don Wollheim, John B. Michel, Will Sykora, Hahn, David Kyle, Goudket, and Fred Pohl) visited the Philadelphia Branch (including Milt Rothman, Bob Madle, and Ossie Train) for a tour of town and then a get-together at Milt Rothman's house for an afternoon. It was "marked with horseplay and camaraderie". Milt Rothman was elected convention chairman and Fred Pohl secretary. The only other official business was to plan the Second Eastern Convention for New York in February 1938.
