Otto Bremer came to Minnesota as a German immigrant in 1886 seeking opportunities for a good life. Over the next 36 years, he worked his way up to become chairman of the American National Bank and a dedicated community leader involved in civic, financial, and corporate life. Bremer’s financial acumen led to investments in many independent rural banks in the Upper Midwest. During the Great Depression, Bremer liquidated many of his personal assets to strengthen these banks and help them ride out hard times. He believed that people could survive and flourish if they had help at critical times.

For all his success, Otto did not forget the strengths and hardships of the rural and immigrant experience. His concern for those working to make their lives better, coupled with his commitment to the local banks, became the cornerstone of his long-term vision. In 1943, Otto created Bremer Bank as a bank holding company to consolidate his stake in the community banks, giving the banks the advantage of acting as a group.
