ALPHONSE HENNIN died on August 18, 1908. He was born in Belgium, and after completing his studies in Europe, he proceeded to the United States.
In 1881 he had charge of the chemical laboratory of the North Chicago Rolling Mill, at Chicago.
From 1883 until 1892 he was in the service of the Springfield Iron Company at Springfield, Illinois, in different capacities, but chiefly as chemist, and while with this company from 1889 until 1892 he devoted his whole attention to the question of fuel gas. The results of his studies were published in the Transactions of the American Institute of Mining Engineers, volume xxi., in a paper entitled "The Simultaneous Production of Ammonia, Tar, and Heating Gas."
After leaving Springfield he accepted a position as a chemist with the National Tube Company at McKeesport, and was shortly after appointed metallurgist. He remained in this position until 1900, when he proceeded to the Isle of Elba in the capacity of general manager of the Elba Company's mines and blast-furnaces, which position he held at the time of his death.
