John Arrillaga has done it again, reports say. The real estate developer and longtime Stanford benefactor — whose name already graces an alumni center, athletic facility and recreation center on campus — has recently made a $100 million donation to the University, according to The San Francisco Chronicle. The donation ranks among the largest gifts made to any university from a single individual, The Chronicle said.

Neither the University nor Arrillaga have publicly confirmed the gift, as private universities are not required to disclose donations. According to the Chronicle of Higher Education, only 66 other gifts of $100 million or more have been made since 1967 nationwide. Most, however, were from foundations and were not offered as one-time donations.

Stanford is no stranger to big-money donations, despite the unique nature of Arrillaga’s latest. The University received $400 million from the William and Flora Hewlett Foundation in 2001, and the Lucille Packard Children’s Hospital at the School of Medicine received $100 million from the David and Lucile Packard Foundation in 2001.
