West, who was at the pinnacle of pop culture after Batman debuted in January 1966, only to see his career fall victim to typecasting after the ABC show flamed out, died Friday night in Los Angeles after a short battle with leukemia, a family spokesperson said.

West died peacefully surrounded by his family and is survived by his wife Marcelle, six children, five grandchildren and two great-grandchildren.

“Our dad always saw himself as The Bright Knight and aspired to make a positive impact on his fans’ lives. He was and always will be our hero,” his family said in a statement.

After struggling for years without a steady job, the good-natured actor reached a new level of fame when he accepted an offer to voice the mayor of Quahog —named Adam West; how’s that for a coincidence! — on Seth MacFarlane’s long-running Fox animated hit Family Guy.

On the big screen, West played a wealthy Main Line husband who meets an early end in Paul Newman’s The Young Philadelphians (1959), was one of the first two humans on the Red Planet in Robinson Crusoe on Mars (1964) and contributed his velvety voice to the animated Redux Riding Hood (1997), which received an Oscar nomination for best short film.

Raised on a ranch outside Walla Walla, Wash., West caught the attention of Batman producer William Dozier when he played Captain Quik, a James Bond-type character with a sailor’s cap, in commercials for Nestle’s Quik.

West, who had appeared in many Warner Bros. television series as a studio contract player, was filming the spaghetti Western The Relentless Four (1965) in Europe at the time. He returned to the States to meet with Dozier, “read the pilot script and knew after 20 pages that it was the kind of comedy I wanted to do,” he said in a 2006 interview with the Archive of American Television.

He signed a contract on the spot, only asking that he be given the chance to approve who would play his sidekick, Robin the Boy Wonder. (He would OK the casting of Burt Ward, who had a brown belt in karate but zero acting experience).

“The tone of our first show, by Lorenzo Semple Jr., was one of absurdity and tongue in cheek to the point that I found it irresistible,” West said. “I think they recognized that in me from what they’d seen me do before. I understood the material and brought something to it.

“You can’t play Batman in a serious, square-jawed, straight-ahead way without giving the audience the sense that there’s something behind that mask waiting to get out, that he’s a little crazed, he’s strange.”

The hunky Lyle Waggoner (later of The Carol Burnett Show) and Peter Deyell also tested to play the Gotham City crime fighters, but West and Ward clearly were superior, and Batman debuted at 7:30 p.m. on Jan. 12, 1966, a Wednesday.

The cliffhanger episode would be resolved the very next night — Same Bat-time! Same Bat-channel! The show was originally intended to last an hour, but ABC split it up when it had two time slots available on its primetime schedule.

West said that he played Batman “for laughs, but in order to do [that], one had to never think it was funny. You just had to pull on that cowl and believe that no one would recognize you.”

The series, filmed in eye-popping bright colors in an era of black-and-white and featuring a revolving set of villains like the Riddler (Frank Gorshin), Joker (Cesar Romero), Penguin (Burgess Meredith) and Catwoman (Julie Newmar), was an immediate hit; the Thursday installment was No. 5 in the Nielsen ratings for the 1965-66 season, and the Wednesday edition was No. 10.

Batman was nominated for the Emmy Award for outstanding comedy series in its first year, losing out to CBS’ The Dick Van Dyke Show. A 20th Century Fox movie was rushed into production and played in theaters in the summer before season two kicked off in September 1966.

However, the popularity of the show soon plummeted, and Batman — despite the addition of Yvonne Craig as Batgirl — was canceled in March 1968 after its third season.

West quickly struggled to find work, forced to make appearances in his cape and cowl at car shows and carnivals and in such obscure films as The Marriage of a Young Stockbroker (1971), written by Semple, and The Happy Hooker Goes Hollywood (1980). He and his family downsized, leaving their home in the tony Pacific Palisades for Ketchum, Idaho.

“The people who were hiring, the people who were running the studios, running the shows, were dinosaurs,” the actor said in the 2013 documentary Starring Adam West. “They thought Batman was a big accident, that there was no real creative thought, expertise or art behind it. They were wrong.”

He returned to voice his iconic character in such cartoons as The New Adventures of Batman, Legends of the Superheroes, SuperFriends: The Legendary Super Powers Show and The Simpsons, and Warner Bros.’ long-awaited DVD release of ABC’s Batman in 2014 brought him back into the Bat Signal’s spotlight.

He was born William West Anderson in Seattle on Sept. 19, 1928, the second of two sons. His father, Otto, was a wheat farmer; his mother, Audrey, was a pianist and opera singer.

West attended an all-boys high school, then graduated with a major in English literature from Whitman College. During his senior year, he worked for a local radio station, doing everything from Sunday morning religion shows to the news.

He also starred in a couple of plays at the local theater. “I found that I could move an audience and I was appreciated,” he said.

In the Army, West served as an announcer on American Forces Network television, then worked as the station manager at Stanford while he was a graduate student.

He got a job at a McClatchy station in Sacramento, Calif., then moved to Hawaii, where he hosted a two-hour weekday show in the late 1950s with a diaper-wearing chimp named Peaches. (West said he once interviewed William Holden as the actor was passing through.)

West got a contract at Warner Bros. at $150 a week and was placed in one of the studio’s TV series — Colt .45, Maverick, Hawaiian Eye, 77 Sunset Strip, Cheyenne, etc. — pretty much every week.

He got his first regular TV role when he played Det. Sgt. Steve Nelson under the command of Robert Taylor on the 1959-62 ABC/NBC series The Detectives, coming aboard when that show expanded to one hour in color.

After he split with Warner Bros., West showed up in such forgettable films as Geronimo (1962) starring Chuck Connors, Tammy and the Doctor (1963) with Sandra Dee and in The Three Stooges film The Outlaws Is Coming (1965) before Batman changed his life forever.
