#1 – Alec Wildenstein and Jocelyn Wildenstein – $2.5 Billion
Alec, who died in 2008, was a French art dealer and businessman. During the late 1990s Alec and his wife Jocelyn received huge media coverage due to excessive spending habits. In 1999 they were the centre of media attention once again because of their divorce, which netted Jocelyn $2.5 billion. This didn’t hurt Alec financially that much, as just two years later his father passed away and left him with an additional $10 billion.
