Formed on November 11, 1929, from the merger of Seattle's three largest banks, the First National Bank Group, the Dexter Horton National Bank (founded 1870 by Dexter Horton), and Seattle National Bank, the bank was originally named First Seattle Dexter Horton National Bank. In 1931, the bank changed its name to First National Bank of Seattle, and again in 1935 to Seattle-First National Bank."@en .
