Latin School was formed in 1888 by a group of parents seeking a better education for their children. Mabel Slade Vickery, a teacher from the East Coast, was invited to Chicago to open the school with a small class of ten 10-year-old boys. During the early years, classes were held in private homes on Chicago's near North Side. The parent-owned institution flourished and in 1899, with enrollment of more than 100 boys, the school moved into its own building and officially became Chicago Latin School.
