About Eli Whitney, III

Eli Whitney III (1820-1894), son of the great inventor, assumed control of his father's armory (from his uncles) in 1841. He not only expanded the Armory, but constructed New Haven's first waterworks on the site. The younger Whitney also encouraged homeownership among his workers, making houselots along the Hartford Turnpike (now Whitney Avenue) available at low cost. Many of these still stand.

Working under contract to inventor Samuel Colt, the younger Whitney manufactured the famous "Whitneyville Walker Colts" for the Texas Rangers. The success of this contract rescued Colt from financial ruin and enabled him to establish his own famous arms company. Whitney's marriage to Sarah Dalliba, daughter of the U.S. Army's chief of ordinance, helped to assure the continuing success of his business.

The younger Whitney also organized the New Haven Water Company, which began operations in 1862. While this enterprise addressed the city's need for water, it also enabled Whitney to increase the amount of power available for his manufacturing operations at the expense of the water company's stockholders. A new dam made it possible to consolidate his operations—originally located in three sites along the Mill River—in a single plant. This dam still exists.
