prolific American writer of children's literature whose books, many of them classics, continue to engage generations of children and their parents.

Brown attended Hollins College (now Hollins University) in Roanoke, Virginia, where she earned a B.A. in 1932. After further work at the Writers Laboratory of the Bureau of Educational Experiments (the forerunner of the Bank Street College of Education), she took a job as an editor of children's books in New York City. Encouraged by publisher William R. Scott, she began to try her hand at writing children's books.

Her books were so successful that in 1941 she left Scott's employ to concentrate full-time on writing, sometimes completing five or more children's titles a year. In addition to publishing books under her own name, she used the pen names Timothy Hay, Golden MacDonald, and (in collaboration with Edith Thacher Hurd, another leading author) Juniper Sage. Her works, which ultimately ran to more than 100 titles, were illustrated by Clement Hurd and others. They include such classics as The Runaway Bunny (1942) and Goodnight Moon (1947).

Something of an eccentric, Brown led a somewhat complicated personal life. Following a number of broken engagements, a period of psychoanalysis, and a stormy 10-year relationship with Blanche Oelrichs Thomas Barrymore Tweed (Tweed, Blanche Oelrichs Thomas Barrymore) (pseudonym Michael Strange), she met and fell in love with a much younger man. Their plans to marry never materialized, however. In 1952, while in Nice, she died of complications from an emergency surgery.
