Father of the Industrial Revolution
The 3rd United States patent, granted in 1790 and signed by then President George Washington, was granted to Oliver Evans for his process to automate grist mills.
Oliver's invention allowed grist mills to produce a higher quality flour - with much lower labor expenses.
The Wye Grist Mill was one of the first mills to be automated with the Evans process, still in use today at the Wye Grist Mill.
Oliver Evans also invented the high pressure steam engine, and was the first to design and build a wheeled vehicle powered by an engine.
