Probably not HN's main interest, but Arrillaga is basically the main reason Stanford has sports teams (in particular, funding the football team)- he's basically funded everything they have around that, to say nothing of his other contributions to the school. And amusingly enough, If Silicon Valley has such a thing as a "power couple", Marc Andressen (the new world) and Laura Arillaga (scion of the old world, professor at the GSB) are it.
