Built in 1903 at 228 East Pleasant Street, formerly 228 Clark Street, this home was associated with Adolph Olson Eberhart as he began his political career. Born in Värmland, Sweden, in 1870, Eberhart came to the United States in 1881, worked as a farmhand, attended Gustavus Adolphus College in St. Peter, Minnesota, and moved to Mankato in 1895 to study law under Judge Lorin Cray and become an attorney. He also served as vice president of Widell Construction, a quarry company, was a director of the First National Bank, and became Deputy Clerk for the U.S. District Court in Mankato. In 1898, he married Adele Koke of Mankato, and they had five children. Eberhart was elected to the State Senate in 1902 and 1904, elected Lieutenant Governor in 1906 and 1908, and became Minnesota's 17th Governor after Governor John Johnson died in 1909. He then won two more terms in 1910 and 1912. Because his duties often required him to be in St. Paul, he sold the home in 1913. Later owners frequently shared the large house with boarders, including students and instructors from Mankato Normal School. The house remains a private residence, was added to the National Register of Historic Places in 1980, and was locally designated a Heritage Preservation Landmark in 2013.
