Eugene Ronceray (1869-1938)
1938 Obituary 
EUGENE RONCERAY devoted the greater part of his career to foundry practice, in which industry he was an outstanding figure. He will also be remembered for his work as director of studies at the Foundry High School in Paris, which he himself founded. Much of his long experience was gathered together in a paper, "The Problem of Economic Foundry Production" which he was to have presented to the Institution. His death, however, occurred on 5th December 1938, only four months before the date arranged for the meeting.,
Mr. Ronceray was born in 1869 and received his education at the Ecole Nationale des Arts et Metiers, at Chalons. In 1888, having completed his apprenticeship with the Paris, Lyons and Mediterranean Railway, he entered the drawing office and assisted in the testing department; during this period he also lectured at the Institution Parangon, Paris. He joined the staff of Mr. P. Bonvillain in 1897 as manager, and in 1905 was taken into partnership, the business being styled S. A. des Etablissements Bonvillain et Ronceray. Subsequently Mr. Ronceray became managing director, and he was also president and managing director of the Universal System of Machine Moulding and Machinery Co, Ltd., London.
He published a large number of articles on foundry practice in the technical press and travelled widely in Europe and America both in connexion with his lectures and as an active participant in foundry-men's congresses. He also organized the foundry exhibition at Turin in 1911 and served on the organizing committees of the international congresses in France in 1913 and 1923. In the latter year he inaugurated, in Paris, an international committee in charge of new methods of testing cast iron. In 1924 he founded the Foundry High School, which was the first of its kind. For his services to education he was made an officer of the Legion of Honour.
In recognition of his work for the Association Technique de Fonderie, he was made a life-president, and he was elected an honorary member of a number of other foundry associations throughout the world, and was presented with the J. H. Whiting Gold Medal of the American Foundry-men's Association in 1926.
Mr. Ronceray, who died in his seventieth year, was elected a Member of the Institution 1906.
