James Danforth "Dan" Quayle (born February 4, 1947) is an American politician and was the 44th Vice President of the United States, serving under George H. W. Bush (1989–1993). He served as a U.S. Representative and U.S. Senator from the state of Indiana.

Quayle was born in Indianapolis, Indiana, to Martha Corinne Pulliam and James Cline Quayle. He has often been incorrectly referred to as James Danforth Quayle III. In his memoirs, he points out that his birth name was simply James Danforth Quayle. The name Quayle originates from the Isle of Man.

His maternal grandfather, Eugene C. Pulliam, was a wealthy and influential publishing magnate who founded Central Newspapers, Inc., owner of over a dozen major newspapers such as The Arizona Republic and The Indianapolis Star. James C. Quayle moved his family to Arizona in 1955 to run a branch of the family's publishing empire. While the Quayle family was very wealthy, Dan Quayle was less so; his total net worth by the time of his election in 1988 was less than a million dollars.
