The story in pictures
Eli Whitney Museum, Hamden

The main building of the Eli Whitney Museum, built in 1890 on the grounds of the Eli Whitney Gun Factory in Hamden, Connecticut.
Excavation of the 1860 armory building - Eli Whitney Armory, West of Whitney Avenue, Armory Street Vicinity, Hamden, New Haven County, CT HAER CONN,5-HAM,3-5.tif
Exposure date unspecified; documentation compiled after 1968
In 1798, Eli Whitney secured a federal contract for 10,000 muskets and established an armory on the Mill River between New Haven and Hamden. The museum explains that the site combined a waterfall suitable for power with a tidal river that offered transportation. [CT041-S01][CT041-S02][CT041-S03][CT041-S04]
The armory’s workshops changed over time and were rebuilt after an explosion in 1860. Many older structures were demolished in 1964. The present museum therefore preserves a layered industrial site rather than an untouched factory from Whitney’s lifetime. [CT041-S01][CT041-S02][CT041-S03][CT041-S04]
Whitney's 1798 contract connected a local river site with a national demand for weapons. The location offered two advantages identified by the museum: falling water for power and a tidal connection for transportation. Those advantages help explain why the armory belongs in the history of the Mill River rather than in a biography of one inventor alone. Buildings, waterways and deliveries were parts of the same undertaking. [CT041-S01][CT041-S02][CT041-S03]
The explosion of 1860 and demolitions of 1964 interrupt any easy image of an unchanged Whitney-era factory. Later buildings and archaeological remains must be dated individually. Survey photographs of a barn, a workshop site or the riverbank can show what survived when recorded, but not automatically what stood there in 1798. The museum landscape is consequently a place to follow rebuilding and preservation, with missing structures as much a part of the story as those still visible. [CT041-S01][CT041-S02][CT041-S03]
