Who wrote “Mary Had a Little Lamb”?

One of the earliest and most influential American magazine editors, Sarah Josepha Hale wrote “Mary Had a Little Lamb” in 1830.

In addition to founding the first national women’s magazine, Godey’s Ladies’Magazine, and successfully campaigning to make Thanksgiving a national holiday, she was inspired to write the rhyme by an actual case of a child’s being followed to school by a pet lamb.
