Humason (1828–1875), the "Father of Wasco County", lived in this modest Gothic Revival house from its construction in 1860 until his death.

Originally from Ohio, he worked in law, prospecting, agriculture, and journalism, prior to settling in The Dalles as a prosperous merchant and river transport businessman.

Representing first Oregon City then The Dalles in the territorial and state legislatures, he introduced legislation establishing Wasco County, Multnomah County, and the City of The Dalles.

He also championed a bill to build a canal around the Cascades Rapids to allow Lower Columbia shipping to reach The Dalles, which did not come to fruition in his lifetime.

Humason's other public positions included mayor of The Dalles and Wasco County judge.
