The house's primary significance is its association with Charles Henry Parr, who lived here from 1902, when he had it built, to 1941 when he died.

During World War I the plant produced shells for the United States Army.

After the war they sold their interests in the business and Hart moved to Montana, and Parr went to Wisconsin to work with Conrad Frudden for a few years.

After returning to Charles City, Parr continued his association with Hart-Parr as an engineer.
