Help with boxer identification
 

Hi-
I recently acquired the three photos scanned below and I was wondering if anyone might be able to help determine who the boxer is (assuming it is not some no-name amateur)? The dates shown on the back of the photos are mysterious to me as well. Was this someone who had their photo taken in 1911 and then reused in 1943? Any help that could be provided would be greatly appreciated.
Thanks in advance,
