Edward G. Acheson House, National Historic Landmark residence in Monongahela, US.
The Edward G. Acheson House is a two-story brick building with an L-shaped floor plan and hip roof located on West Main Street. The structure contains the spaces where experimental work took place and maintains its original appearance from its time as both residence and workplace.
Inventor Edward G. Acheson conducted groundbreaking experiments in this house between 1890 and 1895 that led to a revolutionary substance. His work laid the foundation for a new industry and influenced materials science for decades to come.
The residence reflects the achievements of an inventor whose work pushed forward the development of new materials and transformed industrial production. The neighborhood itself still shows signs of this scientific activity and its impact on the local community.
The building is a private residence and a historical marker from the Pennsylvania Historical and Museum Commission that can be viewed from outside. The location is easy to find with signage that explains its significance for visitors.
The discovery took place in the house's original summer kitchen when Acheson fused clay and powdered coke using electric current in an unexpected kitchen environment. This moment led to a substance that would later be used in abrasives, grinding wheels, and industrial applications worldwide.
