LUDWIG See also:MOND (1839-1909)  , See also:British chemist, was See also:born at See also:Cassel in See also:Germany on the 7th of See also:March 1839 . After studying See also:MONDOVI 693 at See also:Marburg under See also:Hermann See also:Kolbe and at See also:Heidelberg under See also:Robert See also:Bunsen, he came to See also:England in 1862 and obtained a position in a chemical See also:works at See also:Widnes, where he elaborated the See also:practical application of a method he had devised for recovering the See also:sulphur lost as See also:calcium sulphide in the See also:black ash See also:waste of the Leblanc See also:alkali See also:process . He became a 'naturalized British subject in 1867 . In 1873 he entered into See also:partnership with See also:Sir See also:John Tomlinson See also:Brunner (b . 1842– ),whom he had met when he was at Widnes, and thus founded the See also:great chemical manufacturing See also:firm of Brunner, See also:Mond & Co . They began to make alkali by the See also:ammonia-soda process, under See also:licence from the Belgian chemist, Ernest Solvay, but at first the venture threatened to prove a failure . Gradually, however, the technical difficulties were overcome and success assured, largely as a result of improved methods worked out by Mond for the recovery of the ammonia . About 1879 he began experiments in the economical utilization of See also:fuel, and his efforts led him to the See also:system of making producer-See also:gas, known by his name (see Gas: II . For Fuel and See also:Power) . Later, while attempting to utilize the gas for the See also:production of See also:electricity by means of a See also:Grove gas See also:battery, he noticed that the See also:carbon monoxide contained in it combined with See also:nickel . The resulting See also:compound, nickel carbonyl, which was described to the Chemical Society in 189o, is both formed and decomposed within a very moderate range of temperature, and on this fact he based a successful process for the extraction of nickel from its ores . A liberal contributor to the purposes of scientific See also:research, Mond founded in 1896 the See also:Davy-See also:Faraday Research Laboratory in connexion with the Royal Institution .

On his See also:

death, which occurred in See also:London on the 11th of See also:December 1909, he bequeathed ,a large See also:part of his collection of pictures to the nation .
