J. W. C. Williams (fl. c. 1850 - 1862) was an American landscape artist active in New York the mid-19th century. He produced several watercolor views of New York Harbor, some of which were subsequently published in Paris by Louis Turgis. We have been unable to identify William's first name or other biographical details. However, a collection of work related to Williams is on record at the Frick Art Reverence Library (80193172 / 100 Williams) that may offer insight into this talented but little-known painter.
