Marj Dusay, a familiar character on soap operas and a frequent guest star on many classic TV shows, passed away on January 28, 2020. 

One of Dusay's most iconic roles was that of Kara in the third-season Star Trek episode, "Spock's Brain." It's one of the most well-known episodes in the fandom, if not the most infamous. We think it's actually pretty charming— read our defense of "Spock's Brain" here.

Dusay delivers one of the most classic lines of original Trek: "Brain and brain— what is brain?!"

Dusay might be best known for her longrunning role in the soap opera Guiding Light as Alexandra Spaulding. Dusay played the character on and off from 1993 until the finale of the show in 2009. 

She portrayed three different femmes fatales on the show Hogan's Heroes and appeared as Blair Warner's mother on The Facts of Life. Other guest-starring appearances include Hawaii Five-O, Mannix, Barnaby Jones, Bonanza and more.

Another notable role was in The Odd Couple episode "What Does a Naked Lady Say To You?" Dusay was the titular naked lady in that 1971 tale.

The actress was 83 years old.

Just heard about the passing of Marj Dusay who played Blair’s mom, Monica Warner. She was absolutely perfect for the part, a seasoned actress and a delightful woman. It was a privilege to call her Facts of Life family. ?
