The poem was published by Sarah Josepha Hale as part of a collection of children's verses in 1830. She had been encouraged to produce this volume by Lowell Mason, who led the founding of school music education in the United States. He was in search of material he could set to music for instruction, and he included "Mary's Lamb" in his Juvenile Lyre, Or, Hymns and Songs, Religious, Moral, and Cheerful, Set to Appropriate Music, For the Use of Primary and Common Schools. This songbook was used in Boston public schools and was probably the first such collection in the United States. Hale's verse is reportedly based on the true story of Massachusetts girl Mary Sawyer, who took her lamb to school and in whose honor the city of Sterling Massachusetts has erected a statue.
