The month of May, just passed, marked the hundredth anniversary of the oldest chartered bank in the State of Wisconsin. The Marine National Exchange Bank of Milwaukee is the result of the merging in 1930 of two pioneer institutions, the National Exchange Bank which was first chartered by Wisconsin in 1855 and the Marine National Bank, chartered under the National Banking Act in 1900, under the free banking act of Wisconsin in 1853, and originally chartered by the legislature of Wisconsin Territory as the Wisconsin Marine and Fire Insurance Co. in 1839.
