6 Lever, William Hesketh
[br]b. 19 September 1851 Bolton, Lancashire, Englandd. 7 May 1925 Hampstead, London, England[br]English manufacturer of soap.[br]William Hesketh Lever was the son of the retail grocer James Lever, who built up the large wholesale firm of Lever \& Co. in the north-west of England. William entered the firm at the age of 19 as a commercial traveller, and in the course of his work studied the techniques of manufacture and the quality of commercial soaps available at the time. He decided that he would concentrate on the production of a soap that was not evil-smelling, would lather easily and be attractively packaged. In 1884 he produced Sunlight Soap, which became the trade mark for Lever \& Co. He had each tablet wrapped, partly to protect the soap from oxygenization and thus prevent it from becoming rancid, and partly to display his brand name as a form of advertising. In 1885 he raised a large capital sum, purchased the Soap Factory in Warrington of Winser \& Co., and began manufacture. His product contained oils from copra, palm and cotton blended with tallow and resin, and its quality was carefully monitored during production. In a short time it was in great demand and began to replace the previously available alternatives of home-made soap and poor-quality, unpleasant-smelling bars.It soon became necessary to expand the firm's premises, and in 1887 Lever purchased fifty-six acres of land upon which he set up a new centre of manufacture. This was in the Wirral in Cheshire, near the banks of the River Mersey. Production at the new factory, which was called Port Sunlight, began in January 1889. Lever introduced a number of technical improvements in the production process, including the heating systems and the recovery of glycerine (which could later be sold) from the boiling process.Like Sir Titus Salt of Saltaire before him, Lever believed it to be in the interest of the firm to house his workers in a high standard of building and comfort close to the factory.By the early twentieth century he had created Port Sunlight Village, one of the earliest and certainly the most impressive housing estates, for his employees. Architecturally the estate is highly successful, being built from a variety of natural materials and vernacular styles by a number of distinguished architects, so preventing an overall architectural monotony. The comprehensive estate comprises, in addition to the factory and houses, a church, an art gallery, schools, a cottage hospital, library, bank, fire station, post office and shops, as well as an inn and working men's institute, both of which were later additions. In 1894 Lever \& Co. went public and soon was amalgamated with other soap firms. It was at its most successful high point by 1910.[br]Principal Honours and DistinctionsFirst Viscount Leverhulme of the Western Isles.Further Reading1985, Dictionary of Business Biography.

7 Messel, Rudolf
SUBJECT AREA: Chemical technology[br]b. 14 January 1848 Darmstadt, Germanyd. 18 April 1920 London, England[br]German industrial chemist.[br]Messel served three years as an apprentice to the chemical manufacturers E.Lucius of Frankfurt before studying chemistry at Zürich, Heidelberg and Tübingen. In 1870 he travelled to England to assist the distinguished chemist Sir Henry Roscoe, but was soon recalled to Germany on the outbreak of the Franco-Prussian War. After hostilities ceased, Messel returned to London to join the firm of manufacturers of sulphuric acid Dunn, Squire \& Company of Stratford, London. The firm amalgamated with Spencer Chapman, and after Messel became its Managing Director in 1878 it was known as Spencer, Chapman \& Messel Ltd.Messel's principal contribution to chemical technology was the invention of the contact process for the manufacture of sulphuric acid. Earlier processes for making this essential product, now needed in ever-increasing quantities by the new processes for making dyestuffs, fertilizers and explosives, were based on the oxidation of sulphur dioxide by oxides of nitrogen, developed by Joshua Ward and John Roebuck. Attempts to oxidize the dioxide to the trioxide with the oxygen in the air in the presence of a suitable catalyst had so far failed because the catalyst had become "poisoned" and ineffective; Messel avoided this by using highly purified gases. The contact process produced a concentrated form of sulphuric acid called oleum. Until the outbreak of the First World War, Messel's firm was the principal manufacturer, but then the demand rose sharply, so that other firms had to engage in its manufacture. Production thereby increased from 20,000 to 450,000 tons per year.[br]Principal Honours and DistinctionsFRS 1912.
