Martin F. Seedorf papers, 1880-2007

The subject files consist of information gathered by Seedorf about various topics on the history of eastern Washington. Files are arranged in a rough chronological order based on the economic and social development of the region. For example, files on ferry boats precedes files on automobiles to reflect the fact that ferries pre-date automobiles in the region. In addition to files on specific topics, this series contains oral histories, manuscripts, and notes for Memories of Grant County, a periodical published by the Grant County Historical Society. This series also contains a file on the Matthews family, the topic of Rita Seedorf's article "Early Days in Waterville with I.W. Matthews."

This series contains brochures for recreation areas impacted by the Columbia Basin Project, materials created by the Grant County Historical Society, maps of Washington and the Big Bend region, and photographs.
