Lois Lenore Lenski Covey was a Newbery Medal-winning author and illustrator of picture books and children's literature. Beginning in 1927 with her first books, Skipping Village and Jack Horner's Pie: A Book of Nursery Rhymes, Lenski published 98 books, including several posthumously. Her work includes children's picture books and illustrated chapter books, songbooks, poetry, short stories, her 1972 autobiography, Journey into Childhood, and essays about books and children's literature. Her best-known bodies of work include the "Mr. Small" series of picture books (1934–62); her "Historical" series of novels, including the Newbery Honor-winning titles Phebe Fairchild: Her Book (1936) and Indian Captive: The Story of Mary Jemison (1941); and her "Regional" series, including Newbery Medal-winning Strawberry Girl (1945) and Children's Book Award-winning Judy's Journey (1947).

The John Newbery Medal, frequently shortened to the Newbery, is a literary award given by the Association for Library Service to Children (ALSC), a division of the American Library Association (ALA), to the author of "the most distinguished contributions to American literature for children". The Newbery and the Caldecott Medal are considered the two most prestigious awards for children's literature in the United States. Books selected are widely carried by bookstores and libraries, the authors are interviewed on television, and master's theses and doctoral dissertations are written on them. Named for John Newbery, an 18th-century English publisher of juvenile books, the winner of the Newbery is selected at the ALA's Midwinter Conference by a fifteen-person committee. The Newbery was proposed by Frederic G. Melcher in 1921, making it the first children's book award in the world. The physical bronze medal was designed by Rene Paul Chambellan and is given to the winning author at the next ALA annual conference. Since its founding there have been several changes to the composition of the selection committee, while the physical medal remains the same.
