In 1883, scientist Ignatius Donnelly made a compelling argument postulating that all of the fires in the area that night were caused by a meteor shower created when Biela’s Comet lost its tail. In defending his theory, he wrote, “At that hour, half past nine o'clock in the evening, at apparently the same moment, at points hundreds of miles apart, in three different States, Wisconsin, Michigan, and Illinois, fires of the most peculiar and devastating kind broke out, so far as we know, by spontaneous combustion. In Wisconsin, on its eastern borders, in a heavily timbered country, near Lake Michigan, a region embracing four hundred square miles, extending north from Brown County, and containing Peshtigo, Manistee, Holland, and numerous villages on the shores of Green Bay, was swept bare by an absolute whirlwind of flame. There were seven hundred and fifty people killed outright, besides great numbers of the wounded, maimed, and burned, who died afterward. More than three million dollars' worth of property was destroyed.
