Eleanor Taylor MacMillan (16 August 1889 – 28 November 1958) wrote the short play Schooldays in the Land of Oz, which was a promotional work sponsored by Reilly & Lee during the 1920s.
Born in The Dalles, Oregon, she was a longtime resident of Portland. MacMillan wrote book reviews, poetry, short stories, and miscellaneous works. The Baby Book, a collection of her verse, was published in 1916.
Outside of literary pursuits, she worked for several advertising agencies and for the child welfare division of the State Public Welfare Department. She served a term as president of the Northwest Poetry Association, and was involved in a range of civic activities.
