Basque names have a way of jumping out at you. I was recently attending a workshop at the SLAC National Accelerator Laboratory, situated on the Stanford University campus, when someone mentioned the Arrillaga rec center. “Arrillaga?” I thought to myself. “Has to be Basque.” Sure enough, John Arrillaga, one of Stanford’s biggest supporters ever, was of Basque ancestry. His story starts off familiarly enough – humble beginnings as the grandson of Basque immigrants. However, he found opportunities to become one of the wealthiest people in the United States.

- John Arrillaga was born on April 3, 1937, in Inglewood, California. His mother, Freda, who was originally from England, had been a nurse while his father, Gabriel, worked in a market. Gabriel traced his ancestry to the Basque Country. John’s grandparents Gabriel Arrillaga and Magdalena Acarregui were both born in the Basque Country, though I haven’t been able to find out where exactly.
- John came from humble beginnings. When he graduated from high school, he had to borrow a suit jacket from his chemistry teacher. However, he was a talented basketball player and went to Stanford University on a basketball scholarship. He graduated from Stanford with a degree in geology, but that wasn’t the end of his basketball career. He played for both the Bilbao Águilas – a chance to explore his Basque roots – and the then San Francisco Warriors in the NBA.
- In the 1960s, Arrillaga began his career in real estate, buying farmland with his partner Richard Peery that they converted into office space. This was at the time when the semiconductor industry was starting to take off and Arrillaga and Peery were a huge part of the development and growth of Silicon Valley, providing the rising tech companies with needed space. Together, they were one of the biggest landlords in the area and in 2020, Arrillaga was listed in the top 400 of Forbes richest Americans, with a net worth of $2.5 billion.
- Arrillaga gave back to his university, Stanford, in numerous ways, contributing to the construction of multiple buildings, including housing for graduate students and rebuilding the football stadium. He also endowed more than 50 scholarships – notable recipients of his scholarships include Tiger Woods, Katie Ledecky, and Christian McCaffrey. He made two donations to the university in excess of $100 million each. As a result, his name has become a fixture around the campus. The Arrillaga Science Center is just one of many buildings that bears his name.
- Arrillaga died on January 24, 2022. His legacy continues on with his children, Laura and John, who continue his life of philanthropy.
