Peterson, Oscar E.

Oscar E. Peterson was born on November 12, 1871, in Knox County, Illinois, to parents Olof Peterson and Sigrid Johnson. After attending Knox College, he worked for eleven years at the Bank of Galesburg before helping organize the State Bank of Victoria in 1903 as its cashier. While advancing his banking career, he studied law and was officially admitted to the Supreme Court of Illinois bar on April 4, 1907.

In 1910–1911, Peterson moved to California to serve as the founding cashier for the newly established Kingsburg Bank, guiding its rapid growth to over $680,000 in deposits by May 1919. Alongside his executive leadership at the financial institution, he served on the bank’s board of directors and worked as a licensed attorney. Married to Jennie Shoreen of Galesburg in 1899, he raised two daughters, Minnette and Millicent, and active family members affiliated with the Swedish Methodist Episcopal Church.
