In March 1870, Dexter Horton (1825-1904) opens the first bank in Seattle. From 1870 to 1875 the bank is located in a small wooden building on northwest corner of Commercial Street (later First Avenue S) and Washington Street. This is the first bank in King County and is the forerunner of Seafirst Bank.

In 1875, the bank moved nearby into Seattle's first stone building.
