1941 The first specialized interest group

"The first known all-women group is founded in Cleveland in 1941, making it A.A.'s inaugural specialized interest group. Women in New York, Minneapolis, Salt Lake City, and San Diego soon follow suit, and by the mid 1940s the ratio of women to men in the A.A. population is roughly one in six. Women's groups light the way for other specialized groups, which will eventually include those for young people, the elderly, gays and lesbians, and doctors, lawyers, and other professionals."

Note:  It is unclear how such groups square with AA tradition on membership requirement and indeed whether such "specialisms" constitute a breach of those principles. cf. Tradition 3.—Our membership ought to include all who suffer from alcoholism. Hence we may refuse none who wish to recover. Nor ought A.A. membership ever depend upon money or conformity. Any two or three alcoholics gathered together for sobriety may call themselves an A.A. group, provided that, as a group, they have no other affiliation.
