Organized in 1917 by B. B. Munsey, G. C. Dunn, P. D. Williams, and E. L. Dupuy, the State National Bank originally was located just off the southwest corner of Collin and Beaton streets. Munsey served as the institution's first president. He was succeeded in 1926 by Isaac N. Cerf, a prominent Corsicana businessman and civic leader. The bank moved to this site in 1926, and in 1933 the accounts and loans of First State Bank of Corsicana were merged with those of State National Bank. Over the years, the bank has been instrumental in the growth of the city and surrounding areas.
