Edward William Ryan (1882 or 1884 – 1923) was a native of Scranton, Pennsylvania, taking a degree in medicine at Fordham University in 1912. He traveled the world before, during, and after the First World War, partly in U.S. uniform, combatting disease and epidemics. He had quite a storied life, despite its short span. He was slated to be executed in Mexico, for example, and was arrested briefly in Budapest when a souvenir unexploded military shell in his suitcase exploded in the train station. Hmmm! See the rest in the linked Pedia of Wiki article, above.
His decorations reflect widespread respect for his services to medicine during the war.
