Note: This card spells DuPont as Dupont.
DuPont had it’s own building at the 1939 New York World’s Fair. The exhibit was designed by Walter Dorwin Teague, and and the tower you see stood at 105 feet tall. It actually is a large scale representation of a laboratory tool used in chemical laboratories. The “Wonder World of Chemistry” showed what chemistry would be like in “The World of Tomorrow.”
An interview with Jeffrey Meikle from the film Tupperware on PBS gives some insight into DuPont’s use of nylon at the exhibit:
“At the New York World’s Fair in 1939, consumer interest was so high that the public essentially directed the presentation of nylon. DuPont had female guides in their pavilion wearing nylon stockings, and women would come up and ooh and ahh, and by the end of the year, the visitors’ demands to see nylon caused DuPont to move it to the main stage. By the 1940 World’s Fair DuPont had an elaborate presentation, with Miss Chemistry coming out of a test tube. DuPont gradually changed the exhibit because of the popular demands for nylon.”
Exhibits on display included a pest control laboratory, rayon yarn spinning, and chemical processes.
