Richard De Soldenhoff (1844-1894)
1894 Obituary 
RICHARD DE SOLDENHOFF died suddenly on July 26, 1894, whilst reading a paper at a meeting of the South Wales Institution of Engineers. Son of the Baron de Soldenhoff, a Polish nobleman, he was born on April 3, 1844, and was in early life an officer in the Russian army. At the time of the last Polish insurrection, he refused to fight against his countrymen, and threw up his commission to join the insurgents. On the failure of the insurrection, he fled to Belgium, and entered as a student at the Lidge School of Mines. There he formed a friendship with Mr. Evence Coppee, and subsequently became a partner in the British branch of that gentleman's business. In this capacity he was widely known as an authority on coke-ovens and on coal-washing.
He was author of numerous papers relating to these subjects, and the manuscript of his last paper prepared for reading at the Brussels Meeting of the Institute was received by the Secretary on the day of his death.
He was elected a member of the Iron and Steel Institute in 1884.
