See also:civil service, and his
See also:mother was the daughter of the Rev .

See also:death leaving his
See also:family with a considerably reduced income, he gave up his
See also:original idea of becoming a
See also:doctor and obtained an
See also:appointment as a
See also:court clerk, which he held till May 1879 . During these twelve years, besides the
See also:work of a busy police court, which brought him into intimate contact with social problems, he found
See also:time to study chemistry, and attended lectures at the
See also:Birkbeck Institute . He set himself to solve the problem of eliminating phosphorus from iron by means of the Bessemer converter, and by the end of 1875 was convinced that he had discovered a method . He communicated his theory to his
See also:cousin, P . C . Gilchrist, who was chemist to iron
See also:works in
See also:Wales, and experiments were made, which proved satisfactory .
See also:Martin, manager of the
See also:Blaenavon Works, gave facilities for conducting the experiments on a larger scale and undertook to help in taking out a patent . In
See also:March 1878, the first public announcement of the
See also:discovery was made at the
See also:meeting of the Iron and
See also:Steel Institute, but without attracting much
See also:attention; and in
See also:September a paper was wiitten by
See also:Thomas and Gilchrist on the "Elimination of Phosphorus in the Bessemer Converter " for the autumn meeting of this institute, but was not read till May 1879 . Thomas, however, made the acquaintance of E .

See also:Vaughan & Co.'s works at
See also:Yorkshire, whom he interested in the
See also:process, and from this time the success of the invention was assured and domestic and
See also:patents were taken out . The " basic process " invented by Thomas was especially valuable on the continent of
See also:Europe, where the proportion of phosphoric iron is much larger than in England, and both in Belgium and in Germany the name of the inventor became more widely known than in his own
See also:country . In
See also:America, although non-phosphoric iron largely predominates, an immense
See also:interest was taken in the invention . But Thomas had been overworking for years, and his lungs became affected . A long
See also:sea voyage and a residence in
See also:Egypt proved unavailing to restore his
See also:health and he died in
See also:Paris on the 1st of
See also:February 1885 . He had what W . E . Gladstone, in a review of the
See also:Memoirs published in 1891, described as an "
