Description -
Keuffel & Esser, Pickett, Dietzgen, and other major slide rule companies often included an instruction manual in the purchase of the instrument. Some donors have provided these booklets and other paper items, such as advertising flyers, directions for cleaning slide rules, warranty certificates, and even cash register receipts.
 
Keuffel and Esser started in New York, selling drawing materials and drafting supplies. In 1876, K & E started selling surveying instruments. The four-story Keuffel and Esser Manufacturing Complex in Hoboken, New Jersey, was completed four years later. K & E was incorporated in 1889. In 1892, the company commissioned the architecture firm of De Lomos & Cordes to build a showroom and offices at 127 Fulton Street in Manhattan. The firm designed an eight-story brick and terra cotta building in the Renaissance Revival style. The building was completed in 1893, and the company occupied it until 1961. It was designated a New York City landmark in 2005.
