Ruth Edna Kelley

Ruth Edna Kelley was an American librarian and author. She is chiefly remembered for The Book of Hallowe'en (1919), the first book-length history of the holiday.

Kelley was born in Massachusetts, the only child of Charles F. Kelley, a carpenter, and his wife Mary. She grew up in Lynn, Massachusetts, and received a master of arts degree.

The Book of Hallowe'en was Kelly's first book. Her second book, A Life of Their Own (1947), dealt with immortality and spirituality.

Kelley died in Marblehead, Massachusetts at the age of 88.
