186. Robert Mcnair
In the wake of Hurricane Harvey, Mcnair, owner of NFL’S Houston Texans, pledged to donate $2 million to relief efforts; fellow NFL owner Robert Kraft (No. 86) immediately said he’d match the pledge with $1 million. McNair bought the Texans for $700 million in 1999, the same year he sold his power generator company Cogen Technologies for $1.5 billion. He and his wife, Janice, donate more than $20 million each year to their educationfocused foundation.
