James Bennett, the brother of Edwin Bennett, emigrated from Woodville in Derbyshire, England in 1835. In 1839 (then aged 27), upon finding clay similar to Derbyshire clay, he founded a pottery in East Liverpool, Ohio. James's brothers Daniel, Edwin, & William joined the business, now called Bennett and Brothers in 1841. The year 1844 saw the business being sold to Thomas Croxhall & Bros. and James, Edwin and Daniel moving to Birmingham, Pennsylvania, leaving William with his own pottery in East Liverpool. In 1846, Edwin moved to Baltimore, Maryland, founding the E. Bennett Chinaware Company. The company then became E. & W. Bennett when William finally left East Liverpool to join Edwin in 1848. In 1856 the name reverted back to just Edwin Bennett Pottery. In 1863, due to the Civil War, Edwin moved his family to Philadelphia, and took up a partnership in William T. Gillinder's glass works, which then became Gillinder and Bennett. Edwin returned to Baltimore in 1867. The business finally became Edwin Bennett Pottery Company in 1890 and in the same year they went into partnership with D.F. Haynes & Son to become Haynes Bennett & Co. only to become D.F. Haynes & Son in 1895. The company was run by Henry Brunt (chief potter and manager) after Edwin's death in 1908. The company finally closed in 1936, during the depression.
