On April 4, 1899, the American Smelting and Refining Company was chartered in the state of New Jersey. This great industrial combine, usually known as ASARCO and frequently referred to as the smelting trust, had consolidated a number of American smelting concerns with production plants east and west of the Mississippi. At its inception, ASARCO controlled 2/3 of America's smelting and refining capacity, although several major firms remained independent of its ownership. Two years later, a second merger took place which brought M. Guggenheim's Sons into the company, absorbing a principal competitor. In turn, Meyer Guggenheim's sons took control of ASARCO after the merger and directed the company's continued expansion. ASARCO's plants dominated much of the Rocky Mountain smelting industry in the early twentieth century, although the severe decline in silver, lead and copper prices which followed the Panic of 1907 and persisted until American entry into World War I forced it to curtail many operations.
The career of Frederick Roeser (fl. 1888-1919) was closely connected to these developments in the American smelting industry. This collection reveals little about Roeser himself; perhaps either a metallurgist or chemist, he served at different times as superintendent of ASARCO's Arkansas Valley and Globe smelting plants in Colorado (the latter near the city of Denver). During the 1890's, he may have lived in Revelstoke, British Columbia; he certainly invested in British Columbian land and mining stock during that decade. The bulk of the collection (and certainly the most valuable portion), however, consists of the various scientific, engineering and administrative reports circulated among ASARCO officials which he must have accumulated while superintending company smelters. The reports, which span a period from 1911 to 1919, discuss various technical procedures for reducing different metals, ASARCO efforts to improve the efficiency of their metallurgical processes, proper design and construction of metallurgical plants and the wages and productivity of employees at ASARCO plants. The reports illustrate developments in the fields of metallurgy, metals refining and industrial design being pursued by one of the most important members of the industry.

Subject matter

Metallurgy, metallurgical plant construction and design, mining engineering

Items of special interest

Reports on the metallurgy of arsenic and arsenic poisoning, 1917-1919, Box 1(1), review of inspection trip to ASARCO smelting plants in February 1916, Box 1(3), report on labor productivity at various ASARCO plants for the period 1908 to 1917, Box 1(6), reports on the design and construction of metallurgical plants between 1916 and 1919, Box 1(8), report on the wages at the Globe (Colorado) plant between 1915 and 1917, Box 1(16).


All items are housed in a single box. The various technical reports are gathered together by subject in separate folders, organized alphabetically. Reports are followed by folders which contain a few pieces of Roeser's personal correspondence, business papers and ephemera, in that order. Last are five notebooks, filled with technical data about mining machinery, engineering, metallurgy and geology. The notebooks are numbered in chronological order.

Material Transferred

  • 75 photographs of a trip to Africa and the Middle East have been transferred to the Photo Archive, where they are stored in Album #277.
