The Louisiana State Museum - Patterson is the official state aviation and cypress sawmill industry museum and houses two important collections documenting state history.

The Wedell-Williams Aviation Collection focuses on the legacy of Louisiana aviation pioneers Jimmie Wedell and Harry Williams who formed an air service in Patterson in 1928. Both men became nationally prominent during what was known as the Golden Age of Aviation. Although both Wedell and Williams perished in plane crashes, their legacy lives on in the memorabilia and planes on display.

The Patterson Cypress Sawmill Collection documents the history of the cypress lumber industry in Louisiana. Lumbering became the state's first significant manufacturing industry. As a result, cypress lumber harvested and milled in Louisiana was shipped in mass quantities across the United States. The town of Patterson was once home to the largest cypress sawmill in the world, owned by Frank B. Williams, and in 1997 the Louisiana State Legislature designated Patterson as the cypress capitol of Louisiana. The exhibit features a variety of artifacts, photographs, and film that tell the story of this important regional industry.
