2017’s Richest Person and How They Made Their Money: REVEALED!

19 and 20. John and Jacqueline Mars, 77 and 81 – Net Worth: $32.4 billion each

Joining the list as the only joint entry, John and Jacqueline Mars are the inheritors of the biggest candy firm in the world, Mars Inc. Their father Forrest Mars Sr. died just before the millenium, leaving them with the keys to the chocolate factory.

Whilst John and Jacqueline don’t actively manage the operations at the confectionary giant, Mars Inc has diversified massively over the past decade, acquiring the Wrigley gum company and pet food giant Iams for a combined price of just under $26 billion. Known for being extremely private, the brother and sister power duo run the Mars Foundation, which looks to give back to important causes around the world. John was also made an honorary knight by the Queen of England at a ceremony at Windsor Castle.
