This appears to be the 1904 graduation photograph of Nicholas Georgieff Katsonnoff of Sophia, Bulgaria, from, I think, Hebron Academy at Hebron, Maine. The photograph was taken by the Harry L. Plummer studio of Lewiston, Maine.
I found him in a 1908/1909 catalog of Oberlin College in Ohio, where he was a junior in the College of Arts and Sciences. It was this listing that gave me his middle name.
Other than that, I haven't had any luck finding out more about him. If you have information, please leave a comment or contact me directly. Thanks!
