Amazon founder Jeff Bezos is on a giving spree.

The second-richest person in the world on Monday committed $100 million to former president Barack Obama’s foundation, Puck News first reported. Separately, the Bezos family pledged $166 million to NYU Langone Medical Center. A spokesperson declined to specify if Bezos himself was involved in the NYU donation, but his parents, Mike and Jacklyn, are quoted in a press release announcing it.

The gifts come on the heels of $96 million in donations from Bezos last week to 32 organizations helping homeless families.

Bezos’s gift to the Obama Foundation is the largest it has ever received. In a press release, the foundation said the donation will honor the late civil rights icon Rep. John Lewis, and as part of the gift, Bezos asked to name the plaza at the Obama Presidential Center, which is currently under construction on Chicago’s South Side, after the civil rights icon.

“Freedom fighters deserve a special place in the pantheon of heroes, and I can’t think of a more fitting person to honor with this gift than John Lewis, a great American leader and a man of extraordinary decency and courage,” Bezos said in a statement. “I’m thrilled to support President and Mrs. Obama and their Foundation in its mission to train and inspire tomorrow’s leaders.”
