The Wharton School at the University of Pennsylvania was named after Joseph Wharton, who donated $100,000 toward the effort in 1881. Meanwhile in 2008, David Booth, who earned his MBA from the University of Chicago Graduate School of Business in 1971, donated $300 million to the school, which was renamed the Booth School of Business. For a look at how much others have donated to U.S. business schools in exchange for naming rights, check out this slideshow from Bloomberg Businessweek.
