Edith Ballinger Price (April 26, 1897–September 29, 1997) was an American writer and illustrator of eighteen childrens' books. Her first book, Blue Magic, was originally published in St. Nicholas Magazine in 1918, and was published in book form by The Century Company in September, 1919. It concerns a seven-year-old invalid named Fen, who is travelling in Egypt and Italy with his family, but who is prevented by his poor health from leaving their yacht. He is befriended by an old family connection who, to amuse him, pretends to be a blue djinn named Siddereticus.
Price was born in New Brunswick, New Jersey and died in Virginia Beach, Virginia.
