Sir George Thomas Beilby

Sir George Thomas Beilby (17 November 1850 – 1 August 1924) was a British chemist.

He was born in Edinburgh, the son of a doctor and educated at Edinburgh Academy and Edinburgh University. In 1869 he joined the Oakbank Oil Company to work in the oil shale industry where he and colleague William Young were able to increase the yield of oil, ammonia and other useful materials from the shale by retorting and fractional distillation improvements. Their Young and Beilby patent retort was patented in 1882.

In 1892 Beilby patented a production method for hydrogen cyanide. This new method used ammonia and coal as starting materials and was able to meet the rising demands on sodium cyanide for the gold leaching by the MacArthur-Forrest process. He became director of the profitable Cassel Cyanide Company and then became a director of the Castner-Kellner Company at Runcorn, for whom he developed their new Wallsend factory.

He was elected a Fellow of the Royal Society in May 1906. His candidacy citation read: Ex-President, Society of Chemical Industry. Scientific Director of Chemical Works in Great Britain, Germany and America. Inventor of Processes for the manufacture of cyanides, ammonia, fuel gas and paraffin oils, which have had an important influence on these industries. Is recognised as an authority on the industrial use of fuel. Has made a special microscopic study of metals and other solids, discovering certain new relations between the crystalline and amorphous states and connecting with these states the widely different properties of metals in their hard and soft conditions. Scientific papers: - 'The Specific Gravity of Paraffin solid, fused, and in solution (Journ Chem Soc, 1883); 'The Nitrogen of Crude Petroleums and Paraffin Oils' (Journ Soc Chem Ind, 1891); 'The Action of Ammonia on Metals at High Temperatures' with Prof G G Henderson (Journ Chem Soc, 1901); 'The Minute Structure of Metals' (Brit Assoc Report, 1901); 'Surface Flow in Crystalline Solids,' and 'The Effects of Heat and of Solvents on Thin Films of Metal' (Roy Soc Proc, vol lxxii, 1903); 'Granular and Spicular Structure in Solids,' and 'The Intensification of Chemical Action by the Emanations from Gold and Platinum' (Brit Assoc Report, 1903); 'The Surface Structure of Solids' (Hurter Lecture, 1903); 'The Hard and Soft States in Metals' (Phil Mag, August, 1904); 'The Action of certain Gases on Glass in the Neighbourhood of Hot Metals,' and 'The Relations between the Crystalline and Amorphous States as disclosed by the Surface Flow of Solids' (Brit Assoc Report, 1904); Technical papers: - 'Production of Ammonia from Minerals' (SCTJ, 1884 and Journ Soc Arts, 1885); 'New Form of Gas Thermometer' (ibid, 1895); ' new System of Cooling Oils for the Extraction of Paraffin' (ibid, 1885); 'The Waste Gases from Oil Stills' with J B McArthur (ibid, 1887); 'Thirty Years of Progress in the Shale Oil Industry' (ibid, 1897); 'Review of the Coal Consumption of the United Kingdom' (ibid, 1899), since brought up to 1904 at the request of the Royal Commission on Coal Supplies; 'The Position of the Cyanide Industry' (International Congress on Applied Chemistry, Berlin, 1903)"

He was knighted in 1916. He died in Hampstead, London in 1924. He had married in 1877 Emma Clarke Newnham; they had a son Hubert and a daughter Winifred who married chemist Frederick Soddy.
