Klaus kept the operation a secret at first, no-one but his wife knew that the operation was performed.
"I was advised by a friend who returned from France a few months ago to try the operation" said Klaus. "Through the aid of a prominent Pittsburgh doctor, who is at the head of one of the largest hospitals here, I had the job done."
Klaus has had offers to fight in England and Belgium and will sail for the latter country next month.
