I think it was Bram who suggested in a comment that Dan R. is now our best chance at getting direct Pittsburgh-Ireland flights started. We'll see. I was thinking of asking how many places Pittsburghers have served as ambassadors.... but the question would rather be where have Pittsburghers have NOT been named ambassadors. It would probably be impossible to categorize the diasporans who went off into the foreign service or by other means became ambassadors.. That list at least includes Roy Atherton, Ambassador to Egypt, and one of the unsung folks who probably made the Camp David accords happen. but how about the lifelong locals who wind up heading overseas.
Just a quick start on such a list: Pittsburgh mayor George Guthrie would go on to be the ambassador to Japan early in the 20th century. Andrew Mellon was ambassador to the UK and McKeesport's Adolph Schmidt would be ambassador to Canada in the 1970's. Can we come up with a list of others?
