Daniel Halsey, described in this document as a mathematical instrument-maker and keeper of a disorderly and immoral house in Boston, appears elsewhere in documents as a "free" African American. He was possibly a descendent of, or more probably, took the name on his freedom of, the family of Joseph Halsey [fl from 1702], also of Boston, and one of a surprisingly small number of Massachusetts craftsmen working before the end of the eighteenth century, who produced nautical scientific instruments. Records are not complete, but it is more than likely that Daniel Halsey is the earliest known African-American navigational instrument-maker. Halsey is recorded as renting a house on Fore Street in the North End of Boston, and he occasionally "took in white lodgers" (Dayton & Salinger).

In January of 1777, Halsey was called as a material witness in the case of the assault and robbery of one of his lodgers, Esther Lahee, and this warrant, or summons, was issued for his arraignment before the next court of sessions on the 28th.

The letterpress form used to record the details of the warrant, is one that had been in use for many years, since all references to "His Majesty" have been scored through. Massachusetts declared independence on the 4th of July 1776.

The Bedford Whaling Museum lists only three navigational instrument makers in Massachusetts from the late 1770s in their archives: Josiah Muller, Joseph Halsey and John Dupee. Silvio A. Bedini, who made a considerable study of the ​'Early American Scientific Instruments and Their Makers', in his book of 1964, points out that the earliest manufactures in the colony were based in and around Philadelphia, which is the case with clockmakers David and Benjamin Rittenhouse and the Chandlee family.
