No place, circa December 1917. Last page of the corporate minutes for The Edison Portland Cement Company. THOMAS A. EDISON (1847-1931) organized the Edison Portland Cement Company on April 15, 1899. The plant utilized ore processing equipment developed for Edison's unsuccessful ore milling venture during the 1890s. In the winter of 1901, the inventor supervised construction of the Edison Portland Cement Company works at Stewartsville, New Jersey, near large limestone deposits. An explosion at the company's coal grinding plant in 1903 resulted in the death of eight workers, including Chief Engineer Edward A. Darling, and the closure of the plant for redesign. By 1905, the company produced 3,000 barrels of cement per day. In 1908, Edison signed a cross-licensing agreement with the North American Portland Cement Company for mutual use of important cement patents. By the mid-1920s, the firm was the fourth largest producer of cement in the U.S. CHARLES EDISON (1890-1969), the eldest of two sons born to Edison and his second wife, Mina Miller, later became a national recognized corporate executive and served as Secretary of the Navy (1940) and Governor of New Jersey (1941-1943). In 1948, Charles, the majority stockholder of Thomas A. Edison, Inc., founded the philanthropic Brook Foundation (renamed the Charles Edison Fund after his death). Lightly soiled at blank right margin. 3 file holes at blank left margin, ¼-inch paper loss to left of each. Overall, fine condition.
