"Some six months after the death of Margaret Wise Brown in November, 1952, Ellen Lewis Buell stated that she was the author of more than seventy books, and pointed out that with her passing the children's book publishing world had lost one of 'its most prolific writers.' An obituary notice gave the number of her publications as one hundred books 'under own name and pseudonyms.' The pseudonyms--Timothy Hay, Golden MacDonald, Juniper Sage--represented, according to Miss Brown, 'clear-cut writing personalities and distinct styles' differing from each other and from Margaret Wise Brown so greatly that, from the first draft of a book, it was perfectly clear to her just which one of her literary personalities was doing the writing. This remarkable statement, the discrepancy in the count of her books, and a curiosity about a writer who could produce in a life span of little more than forty years such a great number of books, be it seventy or one hundred, are the motivations for this paper. Its purpose is to compile from various sources a literary biography of Margaret Wise Brown and to establish the canon of her writing"--Introduction. / Typescript. / "August, 1959." / "Submitted to the Graduate School of Florida State University in partial fulfillment of the requirements of the degree of Master of Arts." / Advisor: Robert Clapp, Professor Directing Paper. / Includes bibliographical references.
