Firm established by Vincent Novello (1781-1861), and taken over by his son Joseph Alfred Novello (1810-1896) in 1830. Henry Littleton joined the firm in 1841, becoming a partner in 1861, when the firm became Novello & Co., and, on J. A. Novello's retirement in 1866, sole proprietor. Having incorporated the firm of Ewer & Co. in 1867, the title was changed to Novello, Ewer & Co., and still later back to Novello & Co., and, on Henry Littleton's death in 1888, his two sons carried on the business.
