1770-1823.
Vallance arrived in Philadelphia from Glasgow Scotland early in 1791. He quickly established his reputation as one of the best engravers in the city. During this period he developed a friendship with James Thackara. In 1791 Vallance married Elizabeth Trenchard, a niece of Thackara's wife Hannah. A partnership with Thackara was established. He engraved banknotes and documents. In addition he was one of the founders, in 1774, of the Association of Artists in America. His wife Elizabeth died in 1798 at the age of 28. Four years later he married again to Margaret Pratt.

GERRITSZ [GERARD, GERARDUS, GHERRITSZOON van ASSUM].
Hessel 1581-1632.
Gerritsz was apprenticed to W. J. Blaeu as an engraver before starting in business on his own account. He worked closely with Petrus Plancius and his merit may be judged by the fact that he was appointed Cartographer to the Dutch East India Company in preference to Blaeu and subsequently held the same position in a newly formed West India Company. With the new company he came into touch with Johannes de
Laet for whom he prepared a number of new maps of America in the latter's Nieuwe Wereldt published in 1625. His most important early work was a chart showing Henry Hudson's discoveries in his voyage of 1610-11: it is the first to give an outline of Hudson's Bay and indicates Hudson's belief that he had found a way to the North West Passage.
