Henry Cabot Lodge, Jr. (July 5, 1902 – February 27, 1985) was a United States Senator from Massachusetts, a U.S. ambassador, and a candidate for Vice President of the United States.
Kennedy appointed Lodge to the position of Ambassador to South Vietnam, which he held from 1963 to 1964.
The author should have stipulated that it was Henry Cabot Lodge Jr.
Henry Cabot Lodge Jr. should really be Henry Cabot Lodge II since he was named after his grandfather and not his father. Junior usually implies that you were named after your father.
