Company history

Frederick Weyerhaeuser and his partners founded Weyerhaeuser Timber Company in 1900 after acquiring 900,000 acres of timberland in Washington. The company bought a sawmill in Everett in 1902 and opened a pulp mill in Longview in 1931, expanding from timber and lumber into pulp and paper. It developed high-yield forestry practices in the 1960s and entered real estate development in 1969.[24]+4

Weyerhaeuser expanded through its acquisition of Canadian forest-products company MacMillan Bloedel in 1999 and its merger with Willamette Industries in 2002. It later narrowed its activities, combining its fine-paper business with Domtar in 2007, selling its containerboard and packaging business in 2008, and separating its homebuilding business in 2014. The company converted to real estate investment trust status in 2010 and merged with timberland owner Plum Creek in 2016, retaining the Weyerhaeuser name.[29]+6 [24]+11
