Henry Grey (1849-1913)
1913 Obituary [1]
HENRY GREY, the inventor of the Grey mill for rolling structural shapes, died at his home in East Orange, New Jersey, on May 4, 1913.
He was born in London in 1849, and went to the United States in 1870, where he found employment in the iron industry, acting for a few years in the capacity of superintendent and manager of various steelworks. He had an interest in a structural mill at Duluth, and was for a number of years connected with the Cleveland Rolling Mill Company. He spent several years in the development of a new method of producing structural shapes, and perfected a mill for rolling them. The first company to develop the process was the Differdingen Iron and Steel Works in Germany, a mill being installed at these works in 1902.
In 1907 the Bethlehem Steel Company installed a Grey mill at its Saucon works at South Bethlehem. The plant differed from that at Differdingen in having two mills—one for roughing and the other for finishing—whereas at Differdingen one mill completed the operation. For the installation of the special plant at Differdingen he was awarded a gold medal, in 1904, by the Soci4t4 d'Encouragement pour l'Industrie National, of Paris.
He was elected a member of the Iron and Steel Institute in 1902.
