Frederick Weyerhaeuser was a prominent, self-made lumber capitalist and millionaire in the Midwest during the Gilded Age. Nicknamed "the Lumber King" and "the Timber King" during a time when lumber ranked alongside iron and the railroads as a source of industry, Weyerhaeuser created a syndicate that controlled millions of acres of timberland. The syndicate also controlled sawmills, paper mills, and processing plants.
