Julius Johan Olson was born in Norway on February 22, 1875. He and his family immigrated to the United States in 1883, and came to Lake Park. He graduated from Detroit Lakes High School in 1897 and from the University of Minnesota College of Law in 1900. He moved to Warren the same year and practiced there until appointed District Judge by Governor Theodore Christianson in November 1930. Olson resigned as District Judge on March 5, 1934 to accept appointment as Associate Justice of the Minnesota Supreme Court, succeeding Homer B. Dibell. He was elected to the same office in November 1934 and thereafter. Due to ill health, he had to retire from the Court in 1948, and he died May 22, 1955 in Warren.
Olson married Caroline L. Sletten in 1909. They had three children: Julius Johan, who died in childhood, Sletten Carl, and Katherine.
