Columbia Business School

Columbia lays claim to half as many Fortune 100 heads as Harvard, but that's still a strong enough showing to rate it second among the B-schools.

It's no surprise that three out of the four CEOs are leading the charge at financial institutions: Columbia has long had a reputation for being a finance powerhouse and a straight path to Wall Street.

The alumni are:

  • Warren Buffett*, Berkshire Hathaway
  • Vikram Pandit, Citigroup
  • Robert Stevens, Lockheed Martin
  • James P. Gorman, Morgan Stanley

    *Buffett has a master's of science in economics.

  • NEXT: Northwestern - Kellogg School of Management
