Actor Adam West, famous for his straight-faced portrayal of the Caped Crusader in the 1960s “Batman” TV series, has died at 88, his family said Saturday on social media.

West died Friday night “after a short but brave battle with leukemia,” the family statement on Facebook said.

“It’s with great sadness that we are sharing this news,” the family said. “He was a beloved father, husband, grandfather, and great-grandfather. There are no words to describe how much we’ll miss him.”

West played the superhero straight for kids and funny for adults. He initially chaffed at being typecast after “Batman” went off the air after three seasons, but in later years admitted he was pleased to have had a role in kicking off a big-budget film franchise by showing the character’s wide appeal.

I'm delighted because my character became iconic and has opened a lot of doors in other ways, too,” he told The Associated Press in 2014.

“He was bright, witty and fun to work with,” Julie Newmar, who played Catwoman to West’s Batman, said in a statement Saturday.

“I will miss him in the physical world and savor him always in the world of imagination and creativity.”

Born William West Anderson in Walla Walla, Washington, he moved to Seattle at age 15 with his mother after his parents divorced.

He graduated from Whitman College, a private liberal arts school, in Walla Walla.

After serving in the Army, he went to Hollywood and changed his name to Adam West, and began appearing on a number of television series, including “Bonanza,” “Perry Mason” and “Bewitched.”

In April 2012, West received a star on the Hollywood Walk of Fame.

Most recently he did the voice of nutty Mayor Adam West in the long-running “Family Guy” series. And in February 2016, West made an appearance on the CBS sitcom “The Big Bang Theory’s” 200th episode, which marked the 50th anniversary of “Batman.”

West was married three times, and had six children. He had homes in Los Angeles and Palm Springs, but he and his wife, Marcelle, spent most of their time at their ranch near Sun Valley, Idaho.
