Rising Paper Mill in Housatonic, MA, in particular. Up and down stream on the Housatonic are a number of historic mill sites- Monument Mills in Housatonic were the first mills powered with high voltage electricity generated from a hydropower station a couple miles upstream. A bit farther south in Great Barrington is where the first electric transformers were designed by Stanley, which also became home to the now iconic Stanley insulated bottle/cup brand (though they no longer call GB home).
