"There are thousands of ingenious Yankees who fiddled with tools and bits and pieces of machinery who are forgotten but whose incremental practical innovations were critical to American progress. And of all the innovators I have looked at, the most classically underrated in my judgment is Oliver Evans (1755- 1819), a Delaware country boy who had almost no formal education and yet gave us the following: the first automatic production line (long before Henry Ford was born); the first wheeled self-propelled vehicle to move on an American road; the first amphibious vehicle; and America’s first effective high-pressure steam engine. Evans conceived of some 80 inventions, including the first refrigerator that used vapor. But the high-pressure steam engine alone was a mighty power in the advancement of America from a rural to an industrial society. Evans designed and built a hundred engines and boilers for American workshops, freeing them—and the young nation they were serving—from the necessity of access to waterpower. Henry Shreve, the master of the Mississippi River, used Evans’s principle for the Washington, the model for a generation of steamboats that opened the West."
Harold Evans is the author of The American Century; his forthcoming book on innovators, They Made America, will be a WGBH documentary series.

In 1802 American inventor Oliver Evans developed a high-pressure steam engine that produced more power and weighed less than earlier models. His design made it practical to use steam power for land vehicles, such as trains, or boats. The mural is set in 1804 and depicts the nation's first steam-powered amphibious dredging scow, using one of Evans's engines, entering the Schuylkill River.
