Henry Livingstone Sulman (c1861-1940), senior partner in Sulman and Picard
1940 Obituary 
Henry Livingstone Sulman, one of the Original Members of the Institute of Metals, died at his home in Croydon on January 31, 1940, aged 79, after a short illness.
Mr. Sulman, was educated at the City of London Middle Class School and University College, where he studied chemistry under Professor A. C. Williamson and Professor Charles Graham.
After some years in industry he set up in private practice in 1893, specializing in metallurgical and research work in connection with recovery processes.
From 1898 to the time of his death, he was the senior partner in the firm of Sulman and Picard, metallurgists.
Early in his career, Mr. Sulman, in association with Dr. F. L. Teed, devised the bromocyanide process for the treatment of complex gold ores, particularly those containing tellurides.
His consulting and research work covered a wide field, but he will be particularly remembered for his pioneer work in connection with froth flotation, of which he was one of the original patentees.
Although he was always insistent that others bore a large share in the early development of this process, he was generally recognized as their leader by his associates. In the course of his work Mr. Sulman travelled widely, visiting South Africa, Western Australia, Malaya, Canada, and lastly Japan, where he advised on antimony recovery.
Mr. Sulman was a Fellow of the Institute of Chemistry, and a Past-President of the Institution of Mining and Metallurgy.
In 1919 the last-named institution awarded him its gold medal and in 1920 he received the Consolidated Gold Fields of South Africa gold medal and premium from the same body.
