Miss Quackfaster

Emily Quackfaster is the secretary of Scrooge McDuck. She was originally hired by Scrooge's Sisters Hortense McDuck and Matilda McDuck. At first Scrooge did not like the idea of having someone on his payroll but he got used to her very quickly. In fact, some stories have revealed that Scrooge has come to depend on Miss Quackfaster. Even though Scrooge is a shrewd businessman and can easily smell profit, running basic organisational jobs in his own office is beyond his capability.

Comics
Miss Quackfaster 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. In the 2010 Boom! Studios Darkwing Duck and DuckTales comics she is shown to still be happily working as Scrooge's secretary and even helps to stop The Phantom Blot and other villains with the other characters when they all "found their inner Donald" and beat back the slime.

DuckTales
On the show DuckTales she was called Mrs. Featherby.
