Annie Turner Wittenmyer was a prominent American leader in social reform and charitable organizations during the 19th century. She is best known for her role as the first National President of the Woman's Christian Temperance Union (WCTU), where she championed the temperance movement and advocated for women's rights. Wittenmyer's commitment to social issues extended beyond temperance; she also served as the seventh National President of the Woman's Relief Corps (WRC), an organization dedicated to aiding Union veterans and their families after the Civil War. Her leadership in these organizations helped to elevate the role of women in social activism and reform movements of the time. In addition to her organizational work, Wittenmyer was a prolific writer, using her pen to advocate for social change and to document the struggles of her contemporaries. Her contributions to literature and social reform have left a lasting impact, as she not only influenced the temperance movement but also paved the way for future generations of women leaders. Wittenmyer's legacy was recognized posthumously when she was inducted into the Iowa Women's Hall of Fame in 2007, honoring her significant contributions to society and the advancement of women's rights.
