Prior to assuming the presidency, Bush served as the 43rd Vice President of the United States from 1981 to 1989. As a member of the Republican Party, he had previously been a Representative, Ambassador and Director of Central Intelligence. During his career in public service, he was known simply as George Bush; since 2001, he has often been referred to as "George H.W.
