‘I Love Lucy’ actress Doris Singleton dead

LOS ANGELES — Actress Doris Singleton, who played Lucy and Ricky Ricardo’s neighbor on “I Love Lucy,” has died. She was 92.

Lucie Arnaz, daughter of Lucille Ball and Desi Arnaz, confirmed the death in a post on her Facebook page. Singleton died Tuesday, the same day as writer-director Nora Ephron, and Arnaz acknowledged them both in her post, writing, “They were loved and appreciated and will be missed.”

Her death also was reported by Variety and the Hollywood Reporter.

Singleton’s character, first called Lillian Appleby and then Caroline Appleby, appeared in 10 episodes. She was Lucy’s neighbor, the wife of a radio station owner.

“She was sort of Lucy’s nemesis” because both had young sons, Singleton said in a 2005 interview for the Archive of American Television of the Academy of Television Arts & Sciences Foundation. “There was a rivalry there but she had to be nice, Lucy had to be nice to Caroline, because her husband owned the radio station.”

Singleton also played Margaret Williams on the 1960s sitcom “My Three Sons” and she appeared on dozens of other TV shows in the 1950s, 60s and 70s, including another Lucille Ball program, “Here’s Lucy,” “Perry Mason,” “All in the Family,” and “Days of Our Lives.”

She was married to comedy writer Charlie Isaacs for 61 years before his death in 2002.
