Name Keuffel & Esser Co.
Details A manufacturer of drafting, surveying, architectural and engineering tools (including the slide rule, a device that they introduced to America) that established itself in Hoboken in 1875. While founded in New York City in 1867 and where it maintained a "Parent Office", by 1880 it began to build what became a complex of buildings for general offices and factories in Hoboken on the north side of Third Street running from Clinton to Adams Streets including the one with a four-sided clock tower in 1907. Company is often referred to as "K&E".

They issued circa 45 editions of their catalog which are the major resource for identifying their production. Many items are marked as "Keuffel & Esser, N.Y." or "K&E, N.Y." They were actually made or assembled in Hoboken. Some products also have the Hoboken name and/or address on them plus on some printed labels and in catalogs, the artist's bird's-eye view of the Hoboken buildings which was captioned "General Office and Factories in Hoboken, N.J."

Not all items were made in Hoboken; some products or parts were imported from Britain, Switzerland and Germany et al (and were marked with the country of origin), but Hoboken served as the point for packaging and distribution. The range of catalogue products was extensive, but they also produced a large number of items that did not appear in their catalogues, such as scientific apparatus, machine tools, government and military orders, etc. It should be noted that dating items and serial numbers related to the their lines is problematic. The company is no longer in business, although its trademarks are owned by another corporation.

The company left Hoboken circa 1967-68 for a new center of operations in Morristown, New Jersey. The building with the clock tower was converted to residential housing in the 1970's, one of the earliest examples of the adaptive re-use of industrial buildings for living. The apartment house is now commonly called The Clock Tower Building.

The information provided below is as published by the source. It should be noted that there are variances in dates relating to Keuffel and Esser.

From National Museum of American History, Behring Center, 2008.

William J. D. Keuffel (1838–1908) and Herman Esser (1845–1908), both recent immigrants from Germany, began in business in New York in 1867, selling drawing materials and drafting supplies. K&E, as the firm was soon known, began offering surveying instruments in 1876, built a three-story factory in Hoboken, New Jersey, in 1880. and was incorporated in 1889.

K&E introduced a new line of surveying instruments in the early 1890s, describing them as "a thorough departure from all the styles of similar instruments previously made," and noting that many of their improvements were "the product of the genius of our Mr. John Paoli." John Paoli was an Italian who lived in Hoboken, and who obtained several patents for such things as the twisted standards of a transit, the compass box, the leveling screws, and a telescope with stadia wires and cross hairs.

K&E obtained control of Young & Sons in 1918, and made it the Y&S department of their firm. K&E ceased production around 1969. [Not correct]

Historical Note:
Wilhelm Johann Diedrich Keuffel and Herman Esser were partners in the firm of Keuffel & Esser which was founded in July 1867 at 79 Nassau St. Manhattan. They were two German immigrants,who were importers and jobbers of drawing materials and mathematical and surveying instruments. Keuffel (1838-1908), born in Walbeck, Germany and was employed in the hardware business in Germany and Birmingham, England, prior to his immigration to Hoboken, NJ, in 1866. The next year he joined with Herman Esser (1845-1908) who was originally from Wuppertal-Elbertfeld. In 1875, the firm was incorporated as Keuffel & Esser Company (also known as K & E) and moved from Manhattan to Third and Grand Street in Hoboken, New Jersey. Wilhelm J. D. Keuffel died in Hoboken, New Jersey in 1908. Herman Esser retired from Keuffel & Esser Co. in 1902. He was back in Bad Godesberg am Rheim, Germany in April of 1902 and died there in April 1908. The company continued to prosper under new leadership.

In the coming decades, Keuffel & Esser began to expand, opening showrooms, offices and new factories in New York, New Jersey, Chicago, St. Louis, San Francisco, Detroit, and Montreal. They first manufactured surveying instruments in 1885 and introduced an innovative new line of surveying equipment in the 1890s. The company's first product was hard rubber curves and triangles. Later products included drafting paper, surveying instruments, and drafting aids such as slide rules. Keuffel & Esser held patents for a wide range of slide rule features, including improved cursor indicators, functions and scales, and the adjustable body mechanism. The company was so successful that in 1965 it went public on NASDAQ. However, in the coming years, rapid changes in technology including the development of calculators, CAD systems and laser surveying systems, had a detrimental effect on Keuffel & Esser, which shrank drastically after 1972. In 1982 Keuffel & Esser filed for Chapter 11 bankruptcy and eventually was bought out by several companies including Azon Corporation. Currently, Azon Corporation owns the Keuffel & Esser name and trademarks.
