Marilyn Stickle was born on December 18, 1927, in the Bronx, New York City. She married Morris Sachs in 1947 and has two children, Anne and Paul. In 1949 she received her bachelor's degree from Hunter College of the City University of New York, and a master's degree in library science from Columbia University in 1953.

Although her education led to a career as a librarian, first with the Brooklyn, New York Public Library (1949-1960), and then with the San Francisco Public Library (1961-1967), her main avocation has always been as a writer of children's books, writing one or two books almost every year since 1964.

She received an American Library Association Notable Book award for Veronica Ganz, and A Pocket Full of Seeds.

Peter and Veronica, Call Me Ruth, Fourteen, Secret Friends, and Underdog were Junior Literary Guild Selections.
