Amazon founder Jeff Bezos and his wife, MacKenzie, finalised the biggest divorce settlement in history on Thursday, leaving him with 75 percent of their stock in the tech giant and giving her nearly $36 billion in shares. MacKenzie Bezos said she would give all of her stake in The Washington Post and the space exploration firm Blue Origin to her husband -- the world's richest man -- as well as voting control of her remaining Amazon stock. Jeff Bezos, 55, and MacKenzie, 48, a novelist, married in 1993 and have four children. Jeff Bezos founded Amazon in their Seattle garage in 1994 and turned it into a colossus that dominates online retail. According to Forbes magazine, the divorce settlement makes MacKenzie Bezos the third wealthiest woman in the world after L'Oreal heiress Francoise Bettencourt Meyers and Walmart's Alice Walton.
