Richard Nixon was John Carpenter’s final answer when he became the first contestant to win $1 million on the US version of Who Wants to Be a Millionaire? on November 19, 1999.

What was the million-dollar question about?
The final question concerned the American president who had appeared on the television comedy series Rowan & Martin’s Laugh-In. Carpenter identified Richard Nixon. Host Regis Philbin then confirmed the win, completing Carpenter’s run of 15 correct answers.
Why did John Carpenter call his father?
Carpenter reached the final question with all three lifelines still available. He then used Phone-a-Friend to call his father. He already knew the answer: the call was an opportunity to tell his father that he was about to win the million dollars.
That detail matters when retelling the story. Carpenter did use a lifeline, but he did not use it to obtain an answer. The contrast between the pressure of the final question and his calm family announcement helped make the moment memorable.

The Richard Nixon connection
Nixon’s brief Laugh-In appearance aired on September 16, 1968. He was campaigning for the presidency at the time, rather than serving as president. The Richard Nixon Foundation describes a cameo lasting only a few seconds. More than three decades later, recognising that television appearance helped Carpenter secure the top prize.
