History
John Howard Empson (1849–1926), a confectioner from Cincinnati, founded the cannery and built the building. He is considered a "pioneer in the canning industry". The main crop of the cannery was peas, and Empson received several patents for his pea-canning devices. He also developed an improved pea stock that was both sweeter and smaller. Max Kuner was a pioneer in the pickle industry.

At the turn of the 20th century, the cannery was the largest employer in Longmont, having a considerable economic effect on the region. In 1903, the cannery was producing 300 railroad carloads of canned produce annually, and employed 400 workers. It was used as the warehouse of the Empson Cannery (later the Kuner-Empson Cannery) until the end of 1970.

Historical significance
The warehouse is historically significant as the building symbolizes the final step in locally produced food preserving and processing. It was the single largest building in the area, and it dominated the site on which it was constructed. "For over eighty years it has been symbolic of the cannery itself."
