Thomas Heath's (c1714-1757) first business operated from about 1721 from his address "At the Hercules" or "Hercules & Globe". In about 1742, he entered into business with Tycho Wing. Wing (1696-1750) was the son of astronomer, astrologer, and land surveyor, Vincent Wing (1619–1668). After his father's death Wing continued to publish his father's almanac, which he undoubtedly sold though "Heath and Wing". He was also a surveyor (latterly with his own son Vincent), and taught mathematics, surveying, and navigation.

The later trade card reflects the purchase of the business, presumably shortly after Wing's death, by T. Newman.
