The National Association of Women Pharmacists was founded in London on 15 June 1905, following discussions between Margaret Elizabeth Buchanan and Isabella Skinner Clarke. Early meetings were held at Clarke's home. Membership was restricted to those who had passed the major or minor examination and 50 women joined immediately. By 1912 Buchanan claimed that practically all women practicing pharmacy were members. Buchanan served as its president at one point. The association is supportive of, and collaborates with, the Royal Pharmaceutical Society, but is an independent organisation.
