1904 Obituary 
ERNST BERTRAND died at Kladno, in Bohemia, on October 7, 1904. Born in Silesia on December 5, 1847, he was the son of Carl Bertrand, of Lake Hopatcong, New Jersey. On the death of his father, he studied at the Hanover Polytechnic School. After a short period spent in sugar manufacture and railway construction in America, he became blast-furnace manager for Messrs. Moses Taylor & Franklyn.
In 1873 he proceeded to Europe and succeeded Carl Wittgenstein at the Teplitz rolling-mills, of which works he eventually became head. At the time of his death he was director of the Kladno ironworks, and owned the greater portion of the shares of the company. He was elected a member of the Iron and Steel Institute in 1897, and in that year contributed to the proceedings a paper on the combined open-hearth process, invented by himself, in conjunction with Mr. O. Thiel.
