Henry Harbinson Sinclair Papers
Manuscripts
The Henry H. Sinclair Papers number more than 1,600 items, including diaries, journals, newspaper clippings, and extensive personal and business correspondence. The complete date range is 1802-1937 (bulk dates 1909-1914). Subject matter includes mostly business matters of the Great Western Power Company, Palmer Oil Company, Mt. Hood Railway and Power Company, etc.; diaries and notebooks concerning power plant inspection trips, mostly to the Kern River in California; the Pasadena Tournament of Roses Association; the California to Honolulu yacht races. The collection also includes the papers of his son, Arthur W. Sinclair, pertaining to California Delta Farms, Inc. Call numbers for the papers in this collection are 1 (1) through 8 (4), with the first digit representing the box number and the second digit the folder within the box. For the most part, items are not foldered individually; however, a rolled diploma from Sinclair's membership in the American Institute of Electric Engineers is slightly oversized and housed separately. A more detailed, searchable database of the attached container list is available at The Huntington Library.
