Michael Bradley
(1873/9-ca. 1919)

There were two Michael Bradleys living in Chester, Pennsylvania in 1890, one of them a hotel bartender and maker of edged tools (born in Pennsylvania in February 1879) and the other a laborer in a pipe factory (born in Ireland in May 1873).

According to Canfield (1923), Bradley had a general collection of about 1,200 specimens that was purchased by "a dealer" in 1919. The dealer was George L. English, who at that time was managing the mineralogy department at Ward's Natural Science Establishment in Rochester, New York. A Ward's ad in the American Journal of Science (1919) stated that "the Bradley collection embraces about 2,000 specimens, many of them choice—such things as Dioptase, Emerald, Tyrolese Epidote, and Wulfenite."
