Bezos thanked people for sending in suggestions about what he should spend money on. The following week, Bezos will speak at the Air Force Association conference in National Harbor, an appearance tied to his rocket company, Blue Origin. An Amazon.com Inc. spokeswoman said the $2 billion will all come from Bezos.
Bezos's fortune comes mainly from his stake in Amazon, the diversified online firm which briefly hit $1 trillion in market value this month and is the second most valuable company after Apple. Public donations by the 54-year-old Bezos have been rare, and - with exceptions like a $35 million family donation to the Fred Hutchinson Cancer Research Center - typically on a scale far smaller than the two men just behind him in the wealth rankings, Microsoft co-founder Bill Gates and Berkshire Hathaway's Warren Buffett.
Helping the homeless has also been a focus for Amazon.
"He's a pretty fantastic neighbour, him and [his wife] MacKenzie", said Mary's Place director Marty Hartman.
"We will build an organization to directly operate these schools". The foundation helped fund a fact-finding trip to visit government-subsidized model programs in Boston, New York and New Jersey, according to Tim Burgess, the then a city council member who created the Seattle Preschool Program. In the summer of 2017, Bezos tweeted a request from the masses for philanthropic ideas "at the intersection of urgent need and lasting impact".
Bezos made the announcement Thursday in a tweet and a post on his Instagram account.
Last year, he donated $33 million to fund scholarship for "dreamers", the name given to undocumented children of immigrants who face legal obstacles in attending college or university.
Bezos has yet to sign the Giving Pledge, an initiative launched by Gates encouraging billionaires to commit to giving away most of their wealth. September is Childhood Cancer Awareness month and each year Amazon partners with @ACCOrg to raise awareness of childhood cancer - second leading cause of death for kids in the USA between ages 4 and 14.
