Looks like Bo Sweeney. I started a Wikipedia entry for him: en.wikipedia.org/wiki/Bo_Sweeney

Yup, Bo Sweeney was assistant Secretary of the Interior from 1914, native of Missouri, resident of Seattle. He died 1917, from heart problems.

It sure does appear to be Bo Sweeney. Thanks to both of you.

Another photo by CLINEDINST in the Bain/LOC series:

Bo Sweeney (1862-1917) was a lawyer, and a state representative (D) in Colorado, before moving to Seattle. [2]

If Bain published this photograph ca. 1910-1915, it may have been in relation to the appointment of Bo Sweeney in 1914 as Assistant Secretary of the Interior.
