With more than 57,000 members, American Mensa is the largest national Mensa operating under the auspices of Mensa International Ltd., the organization for people with very high IQs. Mensans range in age from 2-107; are barbers, CEOs, rocket scientists (shocker!), plumbers, and a variety of other professions; and they have a majority of college degrees. BlackEnterprise.com presents nine African American Mensa members who share their reasons for joining the august organization. These images are also on display at the Charles H. Wright Museum of African American History from June 30-July 3 in conjunction with the American Mensa annual conference.
