He was the Principal Bassist for the BSO upon their formation in 1881. They have archive
s and I imagine their is more information there.
Here's some more info about him: His name was Herbert J. Butler and he was born in Connecticut in 1845. He studied music in Berlin and while in Boston he was also a member of "The Orchestra Club" and performed at the Park Theater which is no longer in existence. I also found a newspaper clipping listing pieces he performed on double bass during a recital, but none appear to be his own compositions.
He evidently relocated to Chicago where he played violin in the Herbert Butler Concert Company and taught at the American Conservatory of Music in Chicago from 1909 to 1929.
