The ex-wife of Amazon founder Jeff Bezos just pledged to give half of her $36 billion fortune to charity. When MacKenzie Bezos was just 6 years old, she wrote a 142-page book called The Book Worm. It was later destroyed in a flood, but she never gave up on her writing dreams. At Princeton, she studied under Toni Morrison, earning high praise from the literary legend, who once told Vogue that Bezos was “one of the best students I’ve ever had in my creative writing classes.” MacKenzie went on to publish two novels, but we don’t know her as a novelist; we know her as the ex-wife of Amazon founder Jeff Bezos. And since their split earlier this year, we know she’s one of the richest women in the world, with an estimated $36 billion net worth thanks to a 25 percent stake in Amazon. Mostly a private figure during the company’s meteoric rise, the Bezoses’ divorce has flung MacKenzie, 49, into the spotlight. This week, she added another credential to her résumé: tech philanthropist. On Tuesday, Bezos announced she had signed the Giving Pledge, committing half of her assets — $18 billion — to charity in her lifetime or in her will. Her ex-husband, the world’s richest person, infamously declined to sign the pledge in the nine years since it was founded by acclaimed philanthropic billionaires Bill Gates, Melinda Gates and Warren Buffett. But less than two months into controlling her own fortune, Bezos signed on the dotted line. |
