She was originally hired by Scrooge's Sisters Hortense McDuck and Matilda McDuck. At first Scrooge didn't like the idea of having someone on his payroll but he got used to her very quickly. She first appeared in Uncle Scrooge #36 in the story The Midas Touch (the same story that introduced Magica De Spell), and her last name Quackfaster was first used in Uncle Scrooge #39 in A Spicy Tale. Her name Emily was first used in The Life and Times of Scrooge McDuck Part 11. She was also known as Miss Typefast in some stories and on the show Duck Tales she was called Mrs. Featherby.
