The American Association for the History of Nursing (AAHN) will celebrate 25 years of historical scholarship at its annual conference in Philadelphia, September 25 through 28. The AAHN is a professional organization open to everyone interested in nursing history. Originally founded in 1978 as a historical methodology group, the association was briefly named the International History of Nursing Society. It continues the mission of several precursors such as the Society for Nursing History at Teachers' College and the Nursing Archives Associates at Boston University, which published the Journal of Nursing History. The new AAHN held its meetings in conjunction with American Nurses Association, International Council of Nurses, or National League for Nursing conventions. But in 1984, the AAHN held its first stand-alone conference, which was cosponsored by the University of Virginia. Fall conferences have been held annually ever since. Conferences include peer-reviewed manuscript and poster presentations, book displays, an auction, a business meeting, and a banquet with award presentations. Auction proceeds fund scholarships for students interested in research in the history of nursing.
