Over 70 years have passed since I Love Lucy first aired, yet its charm remains as fresh as the day Lucy Ricardo first stepped into America’s living rooms. The laughter, the mishaps, the heartfelt moments — all brought to life by a cast of unforgettable actors. But today, only one major cast member remains to carry the torch of this television treasure.
Keith Thibodeaux — The Boy Who Played Little Ricky
That last living link is Keith Thibodeaux, known professionally as Richard Keith. As a child, he played Little Ricky Ricardo, the on-screen son of Lucille Ball and Desi Arnaz.
Born in 1950, Keith was already a drum prodigy before joining the show. At just five years old, he was cast in one of the most famous sitcoms of all time — an experience he describes as “magical.” Lucille Ball became a loving maternal figure on set, and Desi Arnaz, who shared his Cuban heritage with Ricky Ricardo, made the young actor feel right at home.
In interviews, Keith has recalled that Lucy would give him birthday presents, take time to check in with him between takes, and even make sure he had his own dressing room. “Lucy was naturally very motherly to me,” he once shared. “Desi made me feel at ease — that was his role.”
The Rest of the Cast — Legends Who Live On in Memory
All of Keith’s on-screen “parents” and neighbors have long since passed:
-
Lucille Ball (Lucy Ricardo) — died in 1989
-
Desi Arnaz (Ricky Ricardo) — died in 1986
-
Vivian Vance (Ethel Mertz) — died in 1979
-
William Frawley (Fred Mertz) — died in 1966
Even beloved recurring cast members like Shirley Mitchell, who played Lucy’s friend Marion Strong, are gone — Mitchell passed away in 2013.
A Role That Became History
While several children portrayed Little Ricky in early episodes, Keith Thibodeaux is remembered as the Little Ricky — the one who grew into the role and appeared in both I Love Lucy and The Lucy–Desi Comedy Hour. His energy, musical talent, and chemistry with the cast made him a standout in a show already filled with stars.
The Keeper of the Flame
Now in his 70s, Keith remains active in sharing his memories of the show, attending fan events, and honoring the legacy of his TV parents. He represents not only the last major surviving cast member but also a living reminder of a time when television brought families together in front of a single glowing screen.
For millions of fans, I Love Lucy isn’t just a show — it’s a warm memory, a safe place to return to. And as long as Keith Thibodeaux is here to share his stories, that golden era of comedy lives on.
