Dear Mr. Grafton, I located a Polish publication from 1954 titled “Leczenie zachowawcze skrzywień porazennych kręgosłupa” written by A. SEYFRIED. Further research indicates this person was likely Lesiak A. Seyfried who also wrote an article in the Rumatologia journal of Warsaw in 1969. Might this be the “U.S. doctor” in the photos?
