He became a professor of History and Political Science, and he's now a Delegate at the Democrat National Conference. Somehow that seems... appropriate.
From MPR Minnesota:
He is, in fact, Don Shaffer (and his wife is Pat). And he is the person on whom the character of Radar O'Reilly was based in the book that later became the movie and TV series M*A*S*H. Richard Hornberger (who took the name Richard Hooker) thinly disguised the characters in the book as soldiers who served with him in an Army field hospital in Pyongyang, Korea. Shaffer was company clerk and a chaplain assistant. When the unit had to "bug out" to escape the advancing Chinese, Shaffer had to drive two USO members. One was Joe DiMaggio.So now you know.
He told me the real "Hot Lips" Hoolihan was "much more beautiful than Ms. Swit," and that the soldier on whom Klinger was based was gay (and was named Springer), but it was the Army that was trying to throw him out , while he wanted to stay in the service.
He served in both Korea and Vietnam and -- after concluding his service in intelligence work -- became a professor of history and political science.
