In 1911 the Boy Scouts announced Camp Fire Girls as its sanctioned sister organization, then a Savannah widow gathered eighteen girls the next spring and called them Scouts. Juliette Gordon Low even offered a merger, which Camp Fire refused. The two groups ran a parallel century, fought over the word in court, and both lost roughly half their members regardless of who they admitted.
Sources disagree on Girl Scout peak membership, either about 3.8 million around 2003 or 3.5 million in the mid-1970s. Recent membership figures are internally inconsistent, and the group's transgender policy is known only through secondary statements.
