Uriah Atherton Boyden (1804 – 1879), an American mechanical engineer who designed a greatly improved water turbine (1844) that was widely used in early industrial factories. The Boyden turbine was the first to be manufactured in commercial quantity in the United States. Boyden greatly improved the performance of the Fourneyron turbine by providing a conical approach passage for incoming water. Two 800 horsepower Boyden turbines, at an old mill site in Cohoes, New York, were designated National Historic Mechanical Engineering Landmarks in 1975. These turbines were most likely the largest, and nearly the most powerful, water turbines ever built in the United States to supply direct mechanical power to a manufacturing plant. Boyden’s estate established Harvard’s Boyden Observatory.
