William T. Morris and Francis Willmore, who had previously worked at Royal Worcester in the UK and Ott & Brewer of Trenton, opened their own business in 1893 as the Columbian Art Pottery, to produce exhibits for the World's Columbian Exposition, also known as the Chicago World's Fair in 1893. They produced both Belleek (indicated by a shield with the intertwined letters M.W.) and quality decorated white ware. In 1901 they had 45 employees. The partnership appears to have ceased circa 1905 with William. T. Morris continuing trading as Morris China Co. until circa 1915.
