Provided by Wikipedia Annie Marion MacLean (1869–1934) was a pioneering American sociologist of the women's Chicago School, and is sometimes referred to as the "mother of contemporary ethnography". She was one of the first women to pursue a professional career in sociology.
Regarded today as a feminist pragmatist, MacLean is particularly remembered for her pioneering work in participant observation, and for her rigorous application of her sociological findings to immediate social problems. She is particularly known for her studies of working and immigrant women. MacLean's work was strongly informed by her association with social reformers such as Jane Addams, as well as founding scholars of sociology such as Albion Small, Charles Henderson, and George Herbert Mead.
