The 1939 New York World’s Fair time capsule was created by Westinghouse as part of their exhibit. It measured 90 inches in height, weighed 800 pounds and had an interior diameter of 6.5 inches. It was constructed of a copper, chromium and silver alloy which Westinghouse named “Cupaloy”, which they claimed was harder than steel. It contained everyday items such as a spool of thread and doll, a Book of Record, a vial of staple food crop seeds, a microscope and a 15-minute RKO Pathe Pictures newsreel. Microfilm spools condensed the contents of a Sears Roebuck catalog, dictionary, almanac, and other texts.
