BAKER, DORSEY SYNGE, physician, banker, was born Oct.
28, 1823, in Centerville, Ill. In 1871 he took steps to organize
a railroad company to build a line from Walla Walla to Wallula.
This road, the first in the territory, was built entirely from his
own means and was finished in 1873.  His principal properties
were The Baker and Boyer bank in Walla Walla; and The Walla
Walla and Columbia River Railroad.
