Romulo had quite a career.
He was President Manuel Quezons PR man (first president of the Philippine Commonwealth, and the leading politician of the 1920s-30s). Later he was a PR asset for the US government, being ubiquitous as the US proxy vote at dozens of international conferences. He was mentioned or quoted every week at least, in the 1940s-60s, but was probably more valuable for his fantastic networking skills, the sort of fellow whom you could ask to go have a quiet talk with someone about to do something imprudent. He knew everyone, and everyone knew him.
Overall he was one of the postwar good guys, a reliable upholder of the Pax Americana. Not well known in the US these days and like pretty much everything Filipino, generally ignored.
I am of the age that well remembers Carlos Romulo. A man I greatly admired in those years with McArthur and when he was appointed to the UN. He stood out among those around him.
