Bidzina Ivanishvili

From 2012 until 2013, this founder of the Georgian Dream political party served as Prime Minister of Georgia. Also a successful businessman, he was one of the world's Top 200 billionaires and his country's wealthiest person, according to a 2010 Forbes magazine ranking.

He earned degrees in economics and engineering from Tbilisi State University and went on to receive his doctorate from the Moscow State University of Railway Engineering.

He grew up in Chorvila, Georgia (then part of the Soviet Union) as the son of a poor factory worker. His marriage to Eka Khvedelidze resulted in three children, two of whom -- including the successful rapper Bera Ivanishvili -- were born with albinism.

During a portion of Ivanishvili's tenure as Prime Minister of Georgia, Mikheil Saakashvili served as the country's president.
