Biographical Note

Albert R. Seep is the president of the Mine and Smelter Supply Company. The company was founded by Eben Smith, a man closely identified with the industrial and mining growth of Colorado. Smith brought one of the first stamp mills across the plains, arriving in Denver on May 26, 1860. After involvement in mining ventures in the Gilpin, Boulder and Cripple Creek Districts, Eben Smith and his son, along with R.J. Cary and his brother and a John L. Oliver, incorporated the Mines & Smelting Co. in 1895, beginning by buying out the Kennedy Pierce Machinery Co. In 1901 Eben Smith and his son sold cut their interests to Albert E. Seep’s father, Joseph Seep of Titusville, Pennslyvania, and later in 1904, the Cary’s sold out to the same party. In 1905 the company was expanded significantly when it acquired the manufacturing rights of the Wilfrey Concentrating Table from A.R. Wilfley, who became a consulting engineer and a director of Mine & Smelter, continuing this association until his death in 1927. Another important contribution to the expansion of the company came about 1912, when Frank E. Marcy, manager of the Salt Lake office of the company began developing the idea of improving ore grinding methods. As a result, the Marcy Ball Mill was developed and several years later, the Marcy Rod Mill. In 1954, Mine & Smelter bought out the Colorado Iron Works Co., one of Colorado’s oldest firms. Founded in 1860, John W. Nesmith, its president for many years, came to Denver in 1861 and became associated with the Colorado Iron Works in 1879. From 1907-1929, the headquarters for the Mine & Smelter Supply Co. were in New York City. When Joseph Seep died in 1936, the stock control was still in the east, but today, it is owned, managed, and controlled from Denver.
