Images of the Jerome (later New Haven Clock Co.) factory in New Haven, CT from around 1845 to the early 1900s.
On April 30, 1866 most of the New Haven factory was destroyed in a fire. Only the sales office and a long building on Hamilton St. survived. This view, therefore, showing the reconstructed factory occupying the entire frontage of Saint John St. post-dates the 1866 fire.
The image above, in addition to featuring prominently on clock labels, also appears in the 1880 New Haven Clock Co. catalog. During the period 1885-1905, the factory expanded to encompass the entire block and also the block to the west. Finally, a birds-eye view (Bing maps) below of the factory as it appeared a few years ago. Demolition of the eastern wing started shortly after this image was taken, and it is now gone.
