Sir Henry Doulton (25 July 1820 – 18 November 1897) was an English businessman, inventor and manufacturer of pottery, instrumental in developing the firm of Royal Doulton.
Born in Vauxhall, Henry was the second of the eight children of John Doulton (1793–1873), a pottery manufacturer, and his wife, Jane Duneau, a widow from Bridgnorth in Shropshire. His brother, Frederick Doulton, became Member of Parliament for Lambeth from 1862 until 1868. His father had become a partner in a pottery business in 1815 but Henry was the most academic of his children. Henry spent two years at the University College School where he developed a love of literature. His father had thought Henry the least likely to join the family business, perhaps being destined for a profession, but in 1835, he joined the firm, as did all his brothers other than Frederick.
One of the first results of his many experiments was the production of good enamel glazes. In 1846 he initiated in Lambeth the pipe works, in which he superintended the manufacture of the drainage and sanitary appliances which have helped to make the firm of Doulton famous.
In 1870 the manufacture of "Art pottery" was begun at Lambeth, using the skills of students from the Lambeth School of Art (later the City and Guilds of London Art School). The company exhibited at the Centennial Exposition of 1876 in Philadelphia. In 1877 works were opened at Burslem, where almost every variety of porcelain and earthenware has been produced. Works have since been opened at Rowley Regis, Smethwick, St Helens, Paisley and Paris. After the Paris exhibition of 1878, Henry Doulton was made a Chevalier of the Légion d'honneur.
