Born in
Hjartdal,
Telemark in
Norway, Aaker emigrated with his parents to the
United States in 1848 and settled in
Waukesha County, Wisconsin. In 1854, Aaker and his family settled in
Winneshiek County, Iowa. During the
American Civil War, Aaker served in the
12th Iowa Volunteer Infantry Regiment. Aaker later lived in
Ridgeway, Iowa and was in the mercantile business. In the years following his marriage in 1869 to Christina Andersdatter Turvold (1849–1922), Aaker grew to become a successful business figure in Winneshiek County, being the operator of a lumber yard. Later he was member of the mercantile firm of Galby and Aaker, dealing in grain throughout the 1870s. In the latter part of that decade Aaker sold his lumber yard and became the owner of the Ridgeway Creamery, which later burned to the ground in March 1884. From 1882 to 1886, Aaker served in the
Iowa House of Representatives and was a
Republican. Aaker died at his home in Ridgeway, Iowa at age 54. ==References==
