![Plummet Lamp K & E Co Marking with Cap Off.JPG - PLUMMET LAMP K & E CO. MARKING - Brass plummet/plumb bob oil lamp, body 6 1/2 in. long with 3 in. dia. gimbal, 11 1/2 in. chains with swivel,complete with wick cap, marked K & E. Co. N.Y. on body for Keuffel & Esser Company in New York, ca. 1880s [The Keuffel and Esser Co., also known as K & E, was a drafting instrument and supplies company founded in 1867 by two German immigrants, William J. D. Keuffel and Herman Esser. It was the first American company to specialize in these products. Keuffel and Esser started in New York, selling drawing materials and drafting supplies. In 1876, K & E started selling surveying instruments likely including the plummet lamp shown here (see ad in 1890 K & E Co. Catalogue). The four-story Keuffel and Esser Manufacturing Complex in Hoboken, New Jersey, was completed four years later. K & E was incorporated in 1889 and in 1892, the company built a showroom and offices at 127 Fulton Street in Manhattan. The building was completed in 1893, and the company occupied it until 1961. It was designated a New York City landmark in 2005. In the first decade of the 20th century, Keuffel and Esser introduced a new line of surveying instruments based on the work of John Paoli, an Italian immigrant in Hoboken. A new Keuffel and Esser Manufacturing Complex was built in 1906. In 1891, K & E started manufacturing slide rules. The company produced the 4139 Cooke Radio Slide Rule, designed in the mid-1930s by Nelson M. Cooke, of the Navy's Radio Materiel School, thousands of which were made. The K & E 4081-3 Log-Log Duplex Decitrig was a mainstay for engineering students and practicing engineers in the 1940s, 50s, and 60s. With the advent of the electronic, transistorized calculator in the 1970s, slide rules became obsolete for most uses. Slide rules had never been very profitable for K & E, so it was not difficult to discontinue the line. K & E's market share shrank because of other technological advancements, and the firm shut down its slide-rule engraving machines in 1975. Keuffel and Esser was acquired by AZON Corp. in 1987 after 120 years in business.]](Plummet Lamp K & E Co Marking with Cap Off.JPG) |
