LOS ANGELES (NYTIMES) - American actor Tony Dow, who became a star at 12 as Wally Cleaver, the barely teenage older brother on the popular comedy series Leave It To Beaver (1957 to 1963), died on Wednesday (July 27) at his home in Topanga, California. He was 77.

His death was confirmed by his manager Frank Bilotta.

On Tuesday, his representatives announced his death erroneously in a Facebook post; it was later deleted, but not before many news organisations, including The New York Times, published obituaries, relying on that post as confirmation of the death.

In May, Dow said he had been diagnosed with liver cancer.

He had gone on to a varied adult career, finding mixed success as an actor, a director, a producer and later a sculptor, but he could never quite shake his association with Leave It To Beaver, a dose of early-life fame that might have contributed to his later struggles with depression.

The central character on the sitcom was the button-cute, trouble-prone Beaver Cleaver, played by actor Jerry Mathers, but whenever Beaver needed the benefit of counsel from someone older and wiser who was not likely to yell at him, he turned to Wally, his only sibling and most trusted confidant.

They shared a bedroom - and an en suite bathroom - in an immaculately kept two-story house in Mayfield, a fictional, walkable, crime-free and apparently all-white American suburb.

Wally was a good student, polite to his elders and a responsible good guy "dripping with decency and honesty", as Brian Levant, executive producer of the 1980s sequel series The New Leave It To Beaver, described him to The Arizona Republic in 2017.

Wally played Chinese chequers with his brother in their room, sometimes went along with his friend Eddie Haskell's misguided pranks and was young enough in the first season to ask, "Dad, if I saved up my allowance, could I buy a monkey?" And he would never "squeal on" the Beav, unless he had to.

As the seasons passed, Wally matured, capturing the attention of adolescent female viewers, but his attitude toward his brother remained largely unchanged.

"What did you go and do that for?" he would ask. And, "Will you stop being nice to me and just go back to being a little creep?"

But when he was talking to his parents, Wally was more thoughtful. As he observed at the end of one episode, "For a little kid like that, a lot of stuff sure goes on in his head."

Leave It To Beaver, which also starred Barbara Billingsley and Hugh Beaumont as the boys' polished, suburban-perfect parents, was on the air from 1957 to 1963, but it endured far longer, in endless reruns and as a pop culture touchstone for the baby boom generation.

Anthony Lee Dow was born in Hollywood, California, on April 13, 1945, the son of John Stevens Dow, a designer and contractor, and Muriel Virginia (Montrose) Dow.

His mother was a stuntwoman in Westerns and had been the movie double for silent screen star Clara Bow.

Tony Dow was an athletic boy who won swimming and diving competitions. In fact, it was a coach who suggested that Tony accompany him to an acting audition, the boy's first.

He had virtually no acting experience when he was cast as Wally Cleaver in Leave It To Beaver.

"I was always a little rebellious," the website The Outsider quoted him as saying in 2021, and success had come so easily.

His face was soon on the cover of magazines aimed at teenage readers. After six years, as the fictional Wally was preparing to go to college, Dow was ready to move on to something new.

He appeared as a guest star on series like Dr Kildare (1963), My Three Sons (1964), Lassie (1968), The Mod Squad (1971), Love, American Style (1971) and Emergency (1972).

He was a regular on Never Too Young (1965 to 1966), a soap aimed at teenage audiences. But he soon realised he had been hopelessly typecast as his Leave It To Beaver character.

In his 20s, he began to suffer from clinical depression, which he described as a "self-absorbing feeling of worthlessness, of hopelessness".

Helped by psychotherapy and medication, he became a spokesman for the National Depressive and Manic-Depressive Association.

"I realise there's a perceived irony about this," Dow told the Chicago Tribune in 1993, acknowledging that his name and face were associated with one of the sunniest series in broadcast history.

But fame was part of the problem.

"If you have anonymity, you can sit in the corner and pout and nobody cares," he said. "But if you're a celebrity, pouting is frowned upon."

Twenty years after Leave It To Beaver went off the air, it returned - in the form of a CBS television movie, Still The Beaver (1983).

It reunited the cast, with the exception of Beaumont, who had died in 1982 at 72.

Wally was by then a lawyer who had married a high school sweetheart. Beaver was going through a messy divorce.

The film became a Disney Channel series for one season and returned on TBS as The New Leave It To Beaver from 1986 to 1989.

The series offered monsters in the closet; mishaps with borrowed cars, bicycles, comic books, football tickets and prom dates; and a seemingly unending supply of flashbacks (clips from the original series).

In the 1990s, Dow turned to directing, hired for episodes of shows such as Coach, Harry And The Hendersons, Babylon 5 and, of course, his own The New Leave It To Beaver.

He directed a television movie, Child Stars: Their Stories (2000), and produced two others, The Adventures Of Captain Zoom From Outer Space (1995) and It Came From Outer Space II (1996).

When he appeared on camera in movies or television later on, it was often with a healthy dose of amused self-awareness.

In actor David Spade's comedy Dickie Roberts: Former Child Star (2003), Dow sang in the front row of a glee club of former child stars.

His last screen role was on a 2016 episode of the anthology series Suspense.

Along the way, Dow also had a contracting business and did visual effects for film. But he found his passion when, in his 50s, he began doing sculpture, working primarily in burl wood and bronze.

In 2008, his sculpture Unarmed Warrior was shown in Paris at the Salon de la Societé Nationale des Beaux-Arts, Carrousel du Louvre.

He was with his first wife, Carol Marlow, from 1969 until their 1980 divorce. He married Lauren Shulkind, a ceramic artist, in 1980.

She survives him, along with his son, Christopher; his brother, Dion; and a granddaughter.

Dow said in the end that he was no longer troubled by the outcome of his early success.

"I felt that way probably from the time I was 20 until I was maybe 40," he said in a 2022 interview on CBS Sunday Morning. "At 40, I realised how great the show was."
