William Young & Sons Transit: The serial # found on the compass face on this transit is 9962 thus dating it from approximately 1917. This transit came originally from the Whalehead Club in Corolla, NC and is believed to have been used in surveying that region in the early 1920's. It is marked Young & Sons, Inc. Philadelphia under the glass on the compass face. William Young is credited with being the first maker of transits in America which he introduced in about 1832. The form of this transit is the same as was used on his catalog cover and literature for close to 100 years before K & E bought out the company in 1918. It also comes with the original stiff-legged tripod, case, and extra lense. Overall the condition is very nice, and it has clear optics. The brass body has mellowed to a nice rich dark patina that looks fine. All motions are free and it seems to be fully operational.Brief History of William J. Young William J. Young (1800-1870) was raised in Philadelphia and, at age 13, apprenticed to Thomas Whitney to learn "The Trade or Mystery of a Mathematical Instrument Maker." Seven years later, having earned his freedom and with $30 in his pocket, Young went into business on his own. Within a few years, his was the leading mathematical instrument shop in the United States. he introduced improved forms of the railroad compass, the solar compass, and the surveyor's transit. And he trained younger men to carry on the tradition. Young was the first American to own a dividing engine--a device for mechanically dividing circles into degrees and minutes. He would not have needed such a complex and costly device just to make compasses, but he would need it to graduate the circles of more precise instruments. Not having the money to purchase a dividing engine from England, Young built his own. He had never seen a dividing engine, but worked from a printed description of an English engine. He would later modify this original engine, and build two others. Young signed his earliest instruments "W. J. Young Maker Philadelphia [or Philad a]." He changed his signature to "Wm. Y. Young Maker Philadelphia [or Philad a]" around 1840, and began marking serial numbers on his instruments around 1853. These numbers began around 3000, and probably indicate the number of Young instruments to date. Analysis of these serial numbers shows that Young produced some 65 instruments per year in the 1850s, with annual production rising to 120 in the early 1900s. While 18th-century American instrument makers tended to work alone, or with an apprentice or two, Young usually had ten or so men in his shop, some apprentices and some journeymen. These men were all highly skilled and commanded relatively high wages. The instruments they produced were substantially more costly than those produced in factories, such as that of W. & L. E. Gurley. William J. Young joined with Charles S. Heller and Thomas N. Watson in 1866, and began trading as William J. Young & Co. The partnership disbanded in 1870, Alfred Young operated the firm as Wm. J. Young & Sons, and Heller went on to form Heller & Brightly. The firm began signing their instruments Young & Sons in 1875, and began using this name in advertisements around 1882. Young & Sons was incorporated in 1917 . Keuffel & Esser obtained control of the firm in 1918, made it the Y&S department of K&E, and moved the operations to the K&E factory in Hoboken, New Jersey.
