Brief mention has already been made of the Chandlee family of clockmakers and instrument makers of the 18th century. The founder of the line and first of interest was Benjamin Chandlee, Sr., who migrated in 1702 from Ireland to Philadelphia, where he was apprenticed to Abel Cottey, clockmaker, and eventually married his daughter. His son Benjamin Chandlee, Jr. (1723-1791), worked as a clockmaker in Nottingham, Maryland, where he produced instruments as well as clocks. A fine example of a brass surveying compass--inscribed with his name, and which is believed to have been made for the Gilpin family in about 1761--is on exhibition in the Chester County Historical Society. He had four sons, and a few years before his death he established the firm of Chandlee & Sons, the name of which was changed to Ellis Chandlee & Brothers a year before he died. The oldest of Benjamin Jr.'s four sons was Goldsmith Chandlee (c.1746-1821). After serving an apprenticeship with his father, Goldsmith moved to Virginia and worked near Stephensburg (now Stephens City). He eventually established himself at Winchester and built a brass foundry and a shop where he produced clocks, surveying compasses, sundials, apothecary and money scales, surgical instruments, compasses, telescopes, and other items in metal. Numerous examples of his clocks and instruments have survived. Their fine quality attests to the claim that he was one of the foremost craftsmen of the 18th century. Several of his surveying compasses exist in modern collections. An instrument (fig. 26) that he made about 1794 for a surveyor named Robert Lyle is in the writer's collection; an almost identical instrument that Chandlee made for Lawrence Augustine Washington, George Washington's nephew, is exhibited in the library at Mount Vernon, Virginia.

In the collection of Ohio Historical Society, Ohio State Museum.] Ellis Chandlee (1755-1816) also was apprenticed to his father, and he worked with his brothers in the shop. He established the firm of Ellis Chandlee & Brothers, in 1790, shortly before his father's death. The firm was dissolved in 1797 when the youngest brother, John Chandlee, left the firm. Ellis continued in partnership with his other brother, Isaac Chandlee (1760-1813), until about 1804, producing clocks, surveying instruments, and other metal articles. Their products were signed "Ellis and Isaac Chandlee, Nottingham," or, in the case of a surveying compass in the collection of the Chester County Historical Society, "E. & I. Chandlee, Nottingham." Isaac Chandlee also produced clocks and instruments under his own name only, for there are a number of surviving clocks and surveying compasses signed in such manner (see fig. 28).[59]
