Today in 1836: The Territory of Wisconsin is established by Congress. This button features Miller's "moon girl" promoting "the champagne of beers," headquartered in Milwaukee, Wisconsin. It's made of a material called celluloid.
Considered the first semi-synthetic plastic, celluloid was invented to replace ivory in billiard balls, but it proved unsuitable for the purpose. This sent its inventor to look for other applications. Because celluloid could be made to imitate expensive or rare materials—such as ivory, tortoiseshell, and mother-of-pearl—it was soon employed in the manufacture of fancy goods affordable for the growing middle class.
