No. 20 Stimson Family
One of the nation’s oldest continuously operating integrated wood products companies, the family’s STIMSON LUMBER COMPANY pre-dates the Civil War. Founder Thomas Douglass (T.D.) Stimson (1827–1898) blazed a trail for six generations of his family. Originally based in Michigan, he sold his Great Lakes holdings in the 1880s and relocated to the Pacific Northwest. Today, Stimson Lumber operates seven mills in Oregon and Idaho and owns significant fir, pine, and cedar operations in Oregon, Idaho, and Montana.
