Engraver, publisher and painter, active in Amsterdam, worked for the Visscher family and eventually took over the business.

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.

1600-73 - ARNOLD COLOM (son) c. 1624-68
Jacob Colom was a printer, bookseller, chart and globe maker who set out to challenge the virtual monopoly held by W. J. Blaeu, then the only chart maker in Amsterdam. His Pilot Guide De Vyerighe Colom published in various formats and languages (with exotic tides) to meet the demands of the time was highly successful and forced Blaeu to revise and enlarge his existing chart books. In spite of Blaeu's efforts, Colom's Guide remained popular with seamen for many years and although the charts were issued in great quantity, they are now extremely rare.
