The Pere Marquette Lumber Company was a lumber, salt, sawyering and merchandising company of the nineteenth century. Its initial purpose was as an asset management company. The holdings were that of James Ludington, a lumber baron. The business firm was the cradle for the development of the city of Ludington, Michigan. The company was an important component of the lumber boom and bust in the area, supplying lumber for hundreds of thousands of homes and other structures in the Midwest. It was one of the largest producers of salt in the state of Michigan. The company was active from 1869 to 1897 and later sold.
