Built nextdoor to his business partner’s summer cottage (last post), Wilhelm (William) J. D. Keuffel, a German immigrant from Saxony, erected this summer cottage in the fashionable German-developed summer colony Elka Park in upstate New York. Keuffel & Esser Company (K&E) was founded by German immigrants Wilhelm J. D. Keuffel and Hermann Esser and manufactured high-quality surveying, drafting, and calculating tools for architects, engineers, surveyors, and building contractors in Hoboken, New Jersey with a sales office in Manhattan. By the early twentieth century, it was one of the largest manufacturers of scientific instruments in the world. Keuffel made good money, and summered in Elka Park for years until his death in 1908. The Queen Anne style Victorian “cottage” features the typical asymmetrical plan, corner towers, varied siding and detailing, and many porches to provide the residents with sweeping views of the distant mountains.
