In 1929, Hoffman-La Roche outgrew its New York offices, prompting the development of a new plant in Nutley, NJ, to manufacture a wide range of products. The Swiss company moved much of its corporate management to the U.S. during WWII.

At its peak, the Nutley plant employed 10,000 people. The former Hoffmann-La Roche in Nutley, NJ, was sold in 2016 to an affiliate of Bloomfield’s Prism Capital Partners and is no longer operational.
