According to the Trenton, NJ City Museum website, Ceramic Art Company (Lenox) - In 1889, Walter Scott Lenox left Willets and went into partnership with Jonathan Coxon, superintendent of Ott & Brewer, and founded the Ceramic Art Company (CAC). This partnership lasted until the spring of 1896 when Coxon sold his interest to Lenox. The company continued as the Ceramic Art Company with the word "Lenox" or 'Belleek' added beneath the CAC mark. In February 1906, the name of the company was changed to Lenox, Inc. It is one of the few Trenton potteries from the 19th century that has survived to the present.
