Northwestern Consolidated Milling Company
Northwestern Consolidated Milling Company was an American flour milling company that operated about one-quarter of the mills in Minneapolis, Minnesota, when the city was the flour milling capital of the world. Formed as a business entity, Northwestern produced flour for the half-century between 1891 and 1953, when its A Mill was converted to storage and light manufacturing.
