The compass card in each of these five instruments is identical, designed for use in the mariner's compass (see fig. 46). A gentleman in the dress of about 1740 stands on the shore using a Davis quadrant. Offshore in the harbor is a schooner of the 1750 period. Minor features of the scene are touched up in red, presumably printed, since they are consistent in all of the cards.
William Williams
Although not one of the earliest instrument makers in Boston, but certainly one of the more significant, was William Williams (1737/8-1792). He was the son of Capt. John Williams, a shopkeeper who died on March 22, 1748, at the age of 41, and who was buried in King's Chapel Burial Ground.[98]
William Williams was born in 1737 or 1738. He was ten years of age when his father died, and he had two brothers and two sisters. His father left a substantial estate of £6,575, of which £4,544/9/4 was for the inventory of the shop merchandise. One of the appraisers for his estate, Jotham Maverick, married the widowed Mrs. Williams less than a year later, on January 20, 1748/9.[99]
In 1770 William Williams established himself as a mathematical instrument maker and clockmaker at No. 1 Long Wharf, at the Crown Coffee House, as it was then known. The shop was located on the corner of State and Chatham Streets, on premises owned by Robert Shillcock.

Williams may have worked as an instrument maker in Marblehead before returning to his native Boston. According to Felt,[100] an instrument maker named William Williams at Marblehead advertised in the Salem newspapers in the early 1770's. However, in 1768 Williams was producing instruments from an address in King Street, Boston. (See figure 48.) An advertisement inserted by Williams appeared in the March 12, 1770, issue of The Boston Gazette. It was this same issue that reported the Boston Massacre. One of the victims was Williams' step-brother Samuel Maverick, the son of his stepfather Jotham Maverick by a first marriage.
In 1773 Williams married Joyce Shillcock, the daughter of his landlord. During the Revolutionary War, Williams saw active service as a private in Captain Mills' company, of Col. Jeduthan Baldwin's regiment of artificers, during the years 1777-1779. In 1780 he served in Captain Pattin's company of General Knox's artillery, which was stationed at West Point.[101]
