Alcorn State University received the largest gift from a single donor in its history.

MacKenzie Scott, an author and philanthropist, made a $25 million donation to the university, the school announced on Tuesday.

“This gift is truly transformational and we are humbled by Ms. Scott’s generosity,” Alcorn President Felecia M. Nave said in a release.

The gift doubles the size of Alcorn’s endowment and allows the university to enhance its academic offerings.

Scott announced this week that she gave $4.1 billion to 384 organizations in all 50 states, just four months after donating $1.7 billion to 116 organizations.

Scott also donated to Tougaloo College and the Mississippi Food Network, according to a list she released this week. It is unclear how much those entities received.

Scott, the ex-wife of Amazon founder Jeff Bezos, is the 18th richest person in the world, with a net worth of over $60 billion. She is also the richest woman in the world.
