MacKenzie Scott is an author and the ex-wife of Amazon founder Jeff Bezos, to whom she was married for 25 years. With a net worth of $54.1 billion, Scott, 50, is the world's 22nd-richest person, according to Forbes Billionaires 2020 List.

Ms. Scott, one of the world’s wealthiest women, has now married Dan Jewett, a science teacher at a Seattle private school, according to the person. The marriage was revealed in Jewett's Giving Pledge letter posted on March 6, 2021.

Here is everything about MacKenzie Scott and her journey to becoming one of the world’s most notable philanthropists.

MacKenzie and Jeff met in 1992 when they both worked at hedge fund D.E. Shaw. They married the next year and in 1994, they both moved to Seattle and started Amazon. Scott was one of Amazon's first employees and was heavily involved in Amazon's early days, working on the company's name, business plan, accounts, and shipping early orders. When Amazon began to succeed, Scott took a less involved role in the business, preferring to focus on her family and literary career.

This American novelist who has published two novels was a student of author Toni Morrison at Princeton and worked as a research assistant for her. In 2005, Scott wrote her debut novel, The Testing of Luther Albright, for which she won an American Book Award in 2006. Her second novel, Traps, was published in 2013.

The couple divorced in 2019. As part of the divorce settlement, Jeff transferred 25% of his Amazon stake to MacKenzie, which was 4% of the company.

“What would she do with all that money?” people wondered.

It was in 2019, shortly after she announced the terms of the divorce on Twitter, she signed the Giving Pledge, the movement created by Bill and Melinda Gates and Warren Buffett to encourage extremely wealthy people to contribute a majority of their wealth to philanthropic causes.

Now we know. Quietly, stealthily, and without any publicity (well, until last week, when the news broke), MacKenzie has completely upended the philanthropic world with some of the biggest charitable gifts ever given by a single person.

These donations went to colleges and universities that many people have never heard of, and that tended to serve regional, minority, and lower-income students.

As Scott wrote on Medium in July 2020, she is determined “to give the majority of my wealth back to the society that helped generate it, to do it thoughtfully, to get started soon, and to keep at it until the safe is empty.”

Scott’s commitment to giving is what led to the emergence of the news of her marriage to Dan Jewett and the Wall Street Journal breaking the story. Jewett added his name to Scott’s Giving Pledge web page Last Saturday.

Jewett also referenced his recent marriage and new wife, noting, “And now, in a stroke of happy coincidence, I am married to one of the most generous and kind people I know—and joining her in a commitment to pass on an enormous financial wealth to serve others.”

Since her divorce, Ms. Scott has given away a major chunk of her fortune. It’s been estimated that, in total, Scott gave away $6 billion in 2020, which experts say might be the most ever given directly to charities in a single year by a living donor.
