Collection Summary


This collection consists primarily of business records and correspondence detailing William Tudor's investments in various gold and copper mining companies located in Arizona, Alaska, and Colorado.

Biographical Sketch

William Tudor was born to Frederic "The Ice King" Tudor and Euphemia Fenno Tudor on September 27, 1848. He was the fourth of six children. He attended Harvard University and graduated in 1871. He married Elizabeth Whitwell (b. 1851), daughter of William Scollay Whitwell and Mary Hubbard, in Paris, France, on May 24, 1873. Together they had five children: Henry Dubois, William, Elizabeth, Delia Aimee, and Mary.

William Tudor had an intense interest in his own genealogy and collected information on his Tudor ancestry. In 1896, he edited and published the diary of his great-great-grandfather, Deacon John Tudor, as Deacon Tudor's Diary. His primary occupation, however, was investing in mines. He served on the Boards of Trustees of many of the mining companies he invested in and held positions as an officer in many of them. In 1908, Tudor became the treasurer of the Salida Copper Company, in which he held a very large share. In July 1909, Salida Copper Company bought out Sedalia Copper Company. In October, Tudor traveled to Salida, Colorado, to inspect the companies' mines. In 1910, the Mountain Mining Company, a spin-off of the Salida Copper Company, was formed, and in January 1911, Tudor became its president. In 1913, Tudor became treasurer of the Shawmut Consolidated Copper Company.

Although Tudor owned homes in Hancock, New Hampshire, and Auburndale, Massachusetts, his primary business address was the St. Botolph Club in Boston. He did a great deal of traveling, inspecting mines in Juneau, Alaska, and Salida, Colorado, and he was married and had his first child in Paris, France. He painted for relaxation. William Tudor died in 1923.

Collection Description

The William Tudor papers consist of business correspondence; a large number of letters, telegrams, maps, notes, and receipts; the shareholder records of the Salida Mining Company and the Lake Superior Copper Company; personal letters and legal correspondence pertaining to the farm he owned in Draketown, Georgia; and a collection of notes and letters describing the Tudor genealogy.

The majority of the collection consists of letters, telegrams, newspaper clippings, receipts, diagrams, and notes detailing William Tudor's transactions and investments in various mining companies. Early focus is on the Windham Bay Mining Company and later on the Salida Copper Company, of which William Tudor was treasurer; the Sedalia Copper Company, where he served as director; the Mountain Mining Company; and Empire Mines. The Mountain Mining Company and Arizona and Georgia Development Company subseries contain the incorporation documents of these two companies.

The bulk of Tudor's personal correspondence consists of genealogical notes and letters documenting his research for the genealogical appendices in Deacon Tudor's Diary. There are also a few personal letters, receipts, and tax and duty records.

Detailed Description of the Collection

I. Business records, 1901-1916

A. Loose papers, 1901-1916

Arranged chronologically.

The bulk of this subseries consists of Tudor's business correspondence related to his investments in mines, including his failed investment in the Windham Bay Mining Company, a gold mining venture based in Juneau, Alaska, beginning in 1901, and his subsequent suit against the president of the company, W. M. Ebner. These records continue through 1909.

From 1909 to 1916, the records in this subseries reflect his investments in various mining companies, including the Salida Mining Company, Sedalia Mining Company, Mountain Mining Company, Empire Mines, Shawmut Consolidated Mining Company, Georgia and Tennessee Mining Company, and the Utah Copper Company. In early July 1909, the Salida Copper Company bought the Sedalia Copper Company, but continued to lease land from it, and in October 1910, the Mountain Mining Company paid $3,000 to the Salida Copper Company, although a majority was owned by the Salida Copper Company at the time. Much of the correspondence documents the interrelated nature of the mining industry among these companies.

In 1908 and 1909, Tudor's prospects improved. Salida Copper Company had promising assays from its mines, and he personally inspected them in September and October. By June of 1910, the company had run out of money for capital investments and levied an assessment of 5 cents per share. The officers of the company cast about for large investors. Between June 1910 and January 1912, a great volume of correspondence was sent between Tudor, Leslie Wead (president of Salida Copper Company), and numerous prospective investors. Some of the letters between November and January are rather sharp, as Wead and Tudor realize they have fallen victim to unfulfilled promises. In August 1912, another assessment was levied on the stock.
