Mensa has always encouraged members to congregate around their special interests, both nationally and internationally. Official recognition of American Mensa’s Special Interest Groups began on Sept. 13, 1965, when the first two SIGs were recognized: The Gifted Children Study Group and the Mensa Investment Club.
SIG growth exploded, from 23 to 106, during 1976 under the leadership of Groups Officer Virginia Hourigan. The program expanded almost tenfold from 1975 to 1977 and reached 248 groups in 1980. The organization’s formal SIGs policy was adopted in 1984.
The official birthday for HELL’s M’s followed soon after on Sunday, June 26, 1988. Read more about it on our About page.
