Jeffrey Epstein, the financier arrested in July on charges of sex trafficking of underage girls, died by apparent suicide in a Manhattan jail on Saturday.

Throughout his life, he hobnobbed with world leaders and elite executives, including tech moguls.

The New York Times columnist James B. Stewart published an article on Monday about his August 2018 interview with Epstein. Stewart included Epstein’s thoughts on Silicon Valley and its tech moguls.

“Mr. Epstein then meandered into a discussion of other prominent names in technology circles,” Stewart wrote. “He said people in Silicon Valley had a reputation for being geeky workaholics, but that was far from the truth: They were hedonistic and regular users of recreational drugs. He said he’d witnessed prominent tech figures taking drugs and arranging for sex.”

Here are some of the tech moguls who have been connected to Epstein.

Gates met with Epstein at least once in 2013 to “discuss ways to increase philanthropic spending,” according to CNBC.

CNBC reported that other leaders in philanthropy also attended these meetings and that Gates flew on one of Epstein’s airplanes to Palm Beach, Florida, after their meeting in New York.

In a statement, a representative for Gates, Bridgitt Arnold, told Business Insider: “Although Epstein pursued Bill Gates aggressively, any account of a business partnership or personal relationship between the two is categorically false.”

Stewart said he asked Epstein about a rumor that Musk had asked Epstein to compile a list of candidates to become Tesla’s new chairman.

Musk stepped down from the position in September in the wake of his infamous “funding secured” tweet, which led to a lawsuit from the Securities and Exchange Commission.

“It is incorrect to say that Epstein ever advised Elon or Tesla on anything,” a representative for Musk told Business Insider on Monday.

Musk was also photographed with Ghislaine Maxwell, who’s been accused of being Epstein’s madam, at the 2014 Vanity Fair Oscars Party in West Hollywood.

Musk’s representative told Business Insider that Musk wasn’t posing with Maxwell and that she simply “inserted herself behind him in a photo he was posing for without his knowledge.”

Scott Borgerson, CEO of CargoMetrics

The Daily Mail reported on Wednesday that Maxwell was living in the home of Borgerson, CEO of the tech company CargoMetrics.

But Borgerson told Business Insider that Maxwell was a “former friend” and that she was not living in his house.

“Ghislaine Maxwell is not at my home and I don’t know where she is,” Borgerson told Business Insider.

Marvin Minsky, MIT’s “father of artificial intelligence”

MIT called Minsky, who died in 2016, the “father of artificial intelligence.” He was one of the MIT Media Lab’s founding members.

In a recently unsealed deposition published by The Verge earlier this month, a woman testified that she had been forced to have sex with Minsky at Epstein’s compound in the US Virgin Islands.

The Verge said that while Minsky was known to be a part of Epstein’s circle, the accusation is the first to tie Minsky to Epstein’s sex-trafficking network.
