There’s an episode of The Addams Family called "Morticia, the Decorator," where disapproving neighbors come around the Addams mansion.

This happens many times through the series run, and it was always fun to see the character actors cast to guffaw at the more morose taste of the Addams family.

In this episode, the wife-next-door who was so spooked by her neighbors was played by an actor who arguably took one of Hollywood’s weirdest stage names: Jeff Donnell. And the very same year this Addams Family episode aired, Donnell decided that she liked her stage name so much, she changed her legal name to Jeff, too.

The story behind her unique choice of name begins when Donnell was born Jean Marie Donnell in 1921.

Growing up, she loved to read a popular comic strip called "Mutt and Jeff," which has the distinction of becoming so widely read that its creator Bud Fisher became the first celebrity to make his name in comics.

Debuting in 1907, "Mutt and Jeff," by the time Donnell came to love the comic strip, had placed Fisher in such high demand that he hired assistants like children’s book writer Maurice Sendak - who would later go on to become legend with Where the Wild Things Are - to help get the comic out. (At that point, Sendak was just in high school!)

Later, Donnell decided to take up acting, going to Yale drama school and kicking her career off in the early Forties.

It was at this time that she took the stage name Jeff, in part to give herself a unique name to help her stand out from the crowd and in part as a tribute to her favorite comic strip.

How well do you know the other actor who played Cousin Itt?

It’s said on the day she was asked what her stage name would be, she was reading a "Mutt and Jeff" comic when she glanced up and said "Jeff."

By 1943, Jeff was heralded as "Columbia studio’s best." But every time the credits rolled after one of her movies, movie makers worried audiences would get confused and made sure to give her a special billing so there would be no mistaking the fact that she was "Miss Jeff Donnell."

In the Fifties and Sixties, Jeff began appearing on TV shows like Mister Ed and Perry Mason, perhaps becoming most well-known to television audiences for playing Gidget’s mom.

Then in 1966, after more than two decades as Jeff Donnell on the big and small screen, the actor decided to make the name change permanent, convincing a judge to make it her legal name.

In her career, Donnell was featured in a wide range of movie and TV roles until her death in 1988.

Despite her unusual name and early rave reviews from critics about her potential star power, she told The Arizona Republic in 1959 that she never experienced fame because "nobody recognizes" that gal named Jeff.
