Who invented a bronie?

The brownie, a popular chocolate dessert, is believed to have been invented in the United States in the late 19th century. While there is no definitive inventor, one of the earliest recorded recipes appeared in the 1897 cookbook "The Boston Cooking-School Cookbook" by Fannie Farmer. Another claim attributes the creation of the brownie to a chef at the Palmer House Hotel in Chicago, who made them for the 1893 World's Columbian Exposition.
