Annie Scott Dill Maunder, (1868 – 1947) was an Irish astronomer and mathematician. In 1891 she began work at the Greenwich Royal Observatory, serving as one of the "lady computers" assigned to the solar department. There she assisted E. Walter Maunder, and she spent much time photographing the Sun and tracking the movements of sunspots. She published "The Heavens and their Story" in 1908, with her husband as the co-author. They documented what is now known as the Maunder minimum, a period of extreme quiet on the sun in the late 17th century.
