How ‘I Love Lucy Star’ Elizabeth Patterson Defied Her Family to Become TV’s Favorite Babysitter

Television comedy tends to fall into two distinct camps. There are the rapid-fire joke factories, built around punchlines above all else, and then there are shows where the humor grows naturally out of the characters themselves—people we come to understand well enough that their behavior becomes the comedy. I Love Lucy firmly belongs in that second category, which is a large part of what sets it apart from many of its contemporaries. While the series is anchored by Lucy and Ricky Ricardo (Lucille Ball and Desi Arnaz) and their neighbors Ethel and Fred Mertz (Vivian Vance and William Frawley), its world feels richer because of the recurring players who drift in and out of their lives. Among the most memorable of them is Elizabeth Patterson as Mrs. Trumbull, Little Ricky’s babysitter—a supporting character who, over time, became an essential and much-loved presence in the show’s extended family.

MICHAEL KAROL (author, Lucy A to Z: The Lucille Ball Encyclopedia): “I Love Lucy was so popular in the 1950s, and remains so to this day, that it created a unique show-business paradox: Actors who had long, successful careers before and after they appeared on the show — actors who’d won Oscars (William Holden, Orson Welles), those who went on to become way more famous in other showbiz ventures (producer Aaron Spelling, voice actress Janet Waldo) — are very often recognized most by the public due to their appearances on the classic sitcom. This is the case with Elizabeth Patterson, who had a showbiz career any actor might envy, but is best remembered as the Ricardos’ neighbor, Mrs. Matilda Trumbull, on  I Love Lucy.”

GEOFFREY MARK (author, The Lucy Book: A Complete Guide to Her Five Decades in Television): “Her nickname was Patty Patterson. Nobody called her Elizabeth. She was one of those Dames who had been on radio and the Broadway stage and a million movies, but had never become a star. She was one of those wonderful character people who you saw pretty much everywhere. One example is that while she was Mrs. Trumbull, she was on the George Reeves series The Adventures of Superman.”

Some background on Elizabeth Patterson

Mary Elizabeth Patterson entered the world on November 22, 1874, in Savannah, Tennessee, the daughter of Mildred and Edmund D. Patterson, a lawyer and former Confederate soldier. She was the second of four children, growing up alongside her older sister Annie Belle and younger brothers Edmund and Archie. Her early education took her to colleges in Pulaski and Columbia, where she first discovered a love for performing through campus theater productions. Her parents, however, were far from supportive of that ambition and, hoping to redirect her path, sent her to Europe. The plan backfired. Rather than discouraging her, the experience only deepened her resolve to pursue acting.

Returning home with that determination—and aided by a modest inheritance—Elizabeth set her sights on Chicago, where she joined a theatrical troupe. That decision opened the door to life on the stage, allowing her to tour with repertory companies and begin building the kind of experience that would sustain a remarkably long and varied career.

Patterson made her Broadway debut in 1913 with Everyman, launching a stage career that would span decades. By the time she appeared in His and Hers in 1954, she had amassed 26 Broadway credits, including productions such as Spellbound, Rope, Her Master’s Voice and Yankee Point. At the same time, she was building an equally impressive presence in film, appearing in more than 100 movies between 1926’s The Boy Friend and 1960’s Tall Story.

Despite the rise of television, Patterson largely stayed away from the medium. Outside of I Love Lucy, her small-screen work was limited to just a handful of appearances, including two episodes of The Adventures of Superman and Alfred Hitchcock Presents, making her recurring role as Mrs. Trumbull all the more notable within her otherwise stage- and film-dominated career.

MICHAEL KAROL: “She was one of those dependable character actresses who you would see on screen and go, ‘I know I’ve seen her before!’ In Patterson’s case, she was pretty much everywhere. She often played a neighbor, aunt, grandmother or landlady, and her better-known films include Dinner at Eight [1933], the Bulldog Drummond series in the late 1930s, My Sister Eileen and I Married a Witch [both 1942], Little Women (1949) and Pal Joey [1957].”

GEOFFREY MARK: “She was born in Savannah, Tennessee, which is where she gets that lovely light Southern accent she had. In the 1920s, she was a regular on the Broadway stage but, when talkies came in, they needed women who could actually talk. As a result, people were being hired in the early talkies more for their abilities to speak well than for their looks. And because she had a Broadway career and that wonderful accent, they used her a lot. But she was already 51 years old by the time she got into films and she just continued, playing really wonderful characters, and then she came to play Mrs. Trumbull. She made her first appearance on the show when she was 74 and her last appearance when she was 80.”

MICHAEL KAROL: “Though dainty appearing, almost frail, she was feisty when it was needed, and that unique duality of appearance vs. character made her a Hollywood treasure.”

‘I Love Lucy’

MICHAEL KAROL: “Elizabeth Patterson was initially cast by Lucille Ball and Desi Arnaz in the I Love Lucy episode ‘The Marriage License,’ which first aired April 7, 1952. Patterson played Mrs. Willoughby, wife of a Greenwich, Connecticut justice of the peace who remarries Lucy and Ricky. Patterson memorably warbled an off-key version of ‘I Love You, Truly’ during the ceremony, which was ‘truly’ unforgettable. It must’ve been a snap for Ball after that episode to remember Patterson when the series needed a capable and sympathetic character actress to play the Ricardos’ neighbor, who would be free to babysit Little Ricky when the plot demanded it.”

When Lucille Ball became pregnant, she and Desi Arnaz made the groundbreaking decision to incorporate it into I Love Lucy, turning the storyline into a true cultural phenomenon and ultimately introducing audiences to Little Ricky (first portrayed by Michael Mayer and later Richard Keith). It was in the wake of that shift that Mrs. Trumbull entered the picture, making her debut in the April 20, 1953, episode, “No Children Allowed.”

MICHAEL KAROL: “In that episode, Mrs. Trumbull objected to the presence of Little Ricky, particularly his constant crying in their apartment building, which didn’t allow children. In full curmudgeon mode, Patterson threatened to force the Mertzes to enforce the no-children clause. Ethel stands up for her best friends, but when the Ricardos and Mertzes end up fighting and leave Little Ricky alone in the apartment, Mrs. Trumbull enters and takes control of the situation, Patterson revealing another, nurturing side to the character. As the feuding neighbors realize they left Little Ricky alone, they rush back, only to find him in the arms of Mrs. Trumbull, rocking him gently and cooing, ‘Don’t worry, dear, you’ll never be left alone again.’ The episode had it all; it was hilarious and touching and Patterson made Mrs. Trumbull by turns infuriating and endearing. As a result, she became fast friends with our fab foursome, and was from then on the go-to babysitter for Little Ricky.”

GEOFFREY MARK: “The scripts give us very small pieces of information of trivia. First of all, we know that she is upstairs from the Ricardos when they’re living on the fourth floor. So we now know that the Mertzes’ apartment building is at least five stories — which means that Ricky and Lucy were walking up four flights of stairs to get to the apartment they were in before she gets pregnant. They moved downstairs to the third floor for the rest of the series. Mrs. Trumbull is one or two flights off from them and the roof is above that. She must have been a pretty fit lady to be able to handle that.”

“All of the other characters showed great respect to the Mrs. Trumbull character, which added something to them, because we’re seeing these four people who do crazy stuff, but still respect their elders. They take pleasure at how much she’s able to do at her age and how current she stays with things. They sort of shake their head and smile, like, ‘Wow, this woman still has it,’ which makes us like them even more. That’s called writing good characters.”

An excuse for getting rid of the kid

GEOFFREY MARK: “When Mrs. Trumbull says Little Ricky will never be alone again, it gave them an opening that should they need to get rid of the kid for a plot point—and they used it often—they could say, ‘Oh, the baby’s with Mrs. Trumbull,’ which is a lot better than leaving the kid alone. They were going to need a place to put the child so that the Ricardos don’t look like bad parents. Mrs. Trumbull appeared in every season starting with Season 2, and the reason for that is that she was charming and loving. They wrote a character with heart and that, combined with what Patty brought to the role, made the audience fall in love with her.”

Over the course of a 35-year career in film and television, Elizabeth Patterson built a life that remained closely tied to Hollywood itself—she never married and made her home at the Hollywood Roosevelt Hotel. She passed away on January 31, 1966, at the age of 91, the result of pneumonia.
