Calumet & Hecla Copper Mine is visited by Boston investors in Michigan.

(March) Soon after the visit by Lee, Higginson & Company employee Quincy Shaw takes over as director and fires Edwin Hulbert, who had discovered the mine, prompting him to write, “In my younger days, I became strangely, confidently, and I may add, foolishly, impressed, (with) the significance of an oft quoted phrase, which read, in this way, ‘The solid men of Boston.’” The mine subsequently becomes the largest in the country, producing 90% of the copper in the U.S., and generates enormous dividends for its investors, most of them members of Boston’s leading families. Bliss Perry later writes, “the unwritten history of the public and private benefactions – scientific, artistic, philanthropic – made possible by Calumet & Hecla, and its influence upon certain family histories is a theme worthy of Balzac.”
