Edmond C. (Cornelius) van Diest Papers, Ms 0233

Gift of Alice van Diest 1963, Eloise van Diest Skilling 1988, and Kim Skilling 2024. Accessioned 1986. Finding aid by Ginny Kieffer 1991.

Size: 69 linear feet (104 boxes) plus oversize maps, plans, and drawings in map case drawers (listed at end)

Description: Personal and business correspondence; reports, ledgers and papers relating to mining, engineering, and ranching interests

SCOPE AND CONTENT

The extensive collection of Edmond Cornelius van Diest consists of papers, letters, reports, pamphlets, ledgers and journals, deeds, stocks, publications, addresses, bound copy books and maps and drawings. The collection covers the variety of personal interests, business and engineering matters, civic and personal affairs of E. C. van Diest from 1896 to 1950. These range from mining, real estate, investments, politics, ranching, public service and manufacturing companies, the Chamber of Commerce, the Kiwanis, child welfare, tax reform, Colorado College, Colorado Springs and Colorado Springs Clubs, the Palmer Memorial, the San Luis Valley (the Trinchera and Costilla Estates, mining, family, etc.), and much more.

The bound copy books are copies of letters written by van Diest. Of special interest are the set of letters written by Mr. van Diest when he was agent for General William J. Palmer (many are about Glen Eyrie, Monument Valley Park, Wagon Wheel Gap, timber and other interests of General Palmer). There are also two copy books of letters concerning the Denver and Rio Grande Railroad and two copy books dealing with the San Luis Valley and matters there.

This collection is organized in the order it appeared in the most recent boxes. The materials had been transferred some years ago from van Diest's filing cabinets into the boxes and no doubt some of the order was lost. There is not an overall chronological arrangement by year, nor are they organized by subject, although in many sections there is a sequence that possibly reflects E. C. van Diest’s order. The collection was processed to the folder level not to the individual piece. Subjects are indicated to the folder level with more detail in some places to aid the researcher.

A letter from E. C. van Diest's daughter in the files of Special Collections indicates the School of Mines was given material on the topography and geography of mining interests in Colorado. The Park Department of Colorado Springs also received all maps and identifying material used by van Diest in the layout of the Park System under General Palmer.

BIOGRAPHY

Edmond van Diest was born in Buitenzora, Island of Java, Dutch East Indies (now Indonesia) August 13, 1865, the son of Josephine and Pietre Heinrich van Diest. His father and grandfathers for three generations were governors on the Island of Banca, off Java, for the Dutch Government in the Hague, Holland. The van Diest Family immigrated to the United States in 1872, when Mr. van Diest was seven years of age, where P. H. van Diest had accepted a position with the newly opened Colorado School of Mines as a Meteorologist. He also opened in Denver an assay office where gold from the Cherry Creek Nederlands and Western Slope areas were tested. The family, comprising four sisters and Edmond, were educated in the Denver Public Schools prior to entering Colorado colleges. Upon graduation, with EM-DM degrees, his first positions were connected with the surveying of land boundaries, through which territorial Colorado might become a state. In 1884, he accepted a position as manager of the Sangre De Cristo grant and brought his family to San Luis, Colorado, where he remained with his family until 1904.

In 1890 he married Anna Louise Meyer at Costilla, New Mexico. There were five children, three of whom survived--Alice E. van Diest, professor of Sociology, Colorado College (retired); Annette Josine van Diest Weldie, manager of Personnel, Hermann Hospital, Houston Texas, and wife of Ralph E. Weldie; Eloise Margaret van Diest Skilling, prominent social leader in St. Louis, Missouri and wife of Dr. David M. Skilling, Jr. who is an eminent internist and diagnostician in St. Louis.

In 1904, a close and valued friendship arose between General Wm. J. Palmer and Edmond C. van Diest, resulting in Mr. van Diest becoming consulting and construction engineer for the Palmer interests. Among the jobs handled and accomplished were: the building of Glen Eyrie, the palatial home of General Palmer; the laying out of Monument Valley Park, extending from the northern limits of the city to the business district of Colorado Springs, a matter of 30 blocks; (the Monument Creek which ran through this area was the basis for the Park's development and playground facilities); assistance in the laying out and development of heating facilities for the Colorado College campus.

At the death of General Palmer in 1909, the City of Colorado Springs asked Mr. van Diest to remain as consulting engineer in order that the plans which General William P. Palmer had for the city which he founded might be finished according to earlier specifications.

Beginning in 1910, Mr. van Diest began his interest in public service companies in Colorado, Utah, Montana and Nebraska. His activities covered ice and storage plants, the establishment of public and private utilities, and the specifications for the building of dams and bridges.

Besides a business career, which was related to the development of many western states, Mr. van Diest was always interested in the social and civic organizations of Colorado Springs. Among these was the Chamber of Commerce in which he was not only a local member, but also became a director of the National Chamber of Commerce. He also assisted in the organization of the Colorado-Wyoming Kiwanis Clubs and raised money for the project which studied child welfare in Colorado and which led to the recommendation of the Colorado Kiwanis to the state Legislature in a Child Welfare Department, including grants in aid, home care, recreation, and institutional management. The study which created the recommendations was made by the Child Welfare League of America. Not only was he a trustee for the Colorado School of Mines, with whom he served for a quarter of a century and honored with a Ph. D. degree, but he also served as a trustee of the Colorado College until his death in 1951, being particularly interested in its buildings and grounds, its athletic field, for which he raised money to increase its size and seating capacity, but was also interested in raising of the faculty standards and salaries.

One of Mr. van Diest's projects which has brought about a lasting memory of General Wm. J. Palmer, as well as controversy, was the erection of the bronze statue of the General on his horse on a marble base at the intersection of Platte and Nevada avenues, where federal highways 85-86 and 24 meet. This statue upon its being placed at the above intersection was by Council order to remain in perpetuity until such time as the people in general election should vote to remove and place it in an equally prominent location.

Edmond C. van Diest died in 1950.
