HARTFORD, Conn. — Charles Van Doren, the dashing young academic whose meteoric rise and fall as a corrupt game show contestant in the 1950s inspired the movie “Quiz Show” and served as a cautionary tale about the staged competitions of early television, died Tuesday. He was 93.

He died of natural causes at a care center for the elderly in Canaan, Conn., said his son, John Van Doren. Funeral services will be private.

The scion of a prominent literary family, Van Doren was the central figure in the TV game show scandals of the late 1950s and eventually pleaded guilty to perjury for lying to a grand jury that investigated them. He spent the following decades largely out of the public eye.

“It’s been hard to get away, partly because the man who cheated on ‘Twenty-One’ is still part of me,” he wrote in a 2008 New Yorker essay, his first public comment in years.

Before his downfall, he was a ratings sensation. He made 14 electrifying appearances on “Twenty-One” in late 1956 and early ’57, vanquishing 13 competitors and winning a then-record $129,000. NBC hired him as a commentator.

In a February 1957 cover story on Van Doren, Time magazine marveled at the “fascinating, suspense-taut spectacle of his highly trained mind at work.”

“Just by being himself,” Time wrote, “he has enabled a giveaway show, the crassest of lowbrow entertainments, to whip up a doting mass audience for a new kind of TV idol — of all things, an egghead.”

Later, as the triumph unraveled into scandal, he initially denied he had been given advance answers, but he finally admitted that the show was rigged. He retreated to his family’s home in rural West Cornwall, Conn., after telling a congressional committee in 1959 that he was coached before each segment of the show.

After spending much of the 1960s and ’70s in Chicago, Van Doren and his wife, Geraldine, returned to Connecticut, residing for years in a small brown bungalow on the family compound. They did some teaching but largely lived in semi-seclusion, refusing to grant interviews and even leaving the country for several weeks when Robert Redford’s film “Quiz Show” was released in the fall of 1994.
