Who was the second vice president to James Madison?

James Madison served as President of the United States between 1809 and 1817. His second vice president was Elbridge Gerry (July 17, 1744 - November 23, 1814) who served from March 4, 1813 until his death.

Gerry, whose name was pronounced with a hard G, like the Word "girl", was the namesake of the political process gerrymandering, though this Word has, in time, come to be pronounced with a soft G sound.
