Charles Krug (1846–1929) was a successful rancher and president of the Merchants National Bank. In 1900 at age 54, Krug married Annie A Hackney (1868-1950), the mother of two daughters. They had five more children together. The house was built in 1906 to accommodate the large family.[4][3][5][6]
The NRHP nomination states: "The Krug House is a grand expression of a by-gone age, reminding our current generation of the integrity and perseverance of Charles Krug, and of the timeless values of fine construction that are represented in this eastern Montana home."[3]
