Billionaires Carl Icahn and John Catsimatidis appear in Jeffrey Epstein's 1997 address book

• On July 6, Insider published an never-before-seen address book from 1997 that likely belonged to the late financier and sex offender Jeffrey Epstein.
• The book contains more than 200 names that do not appear in Epstein's original "little black book" from the early 2000s, which was published in 2015.
• Among the new names are New York billionaires Carl Icahn and John Catsimatidis.

The names of two New York billionaires, Carl Icahn and John Catsimatidis, appear in a newly discovered address book, dating to 1997, that likely belonged to the late financier and sex offender Jeffrey Epstein. Insider published the contents of the address book on July 6, the two-year anniversary of Epstein's arrest in 2019.

The 1997 address book predates Epstein's original "little black book" by nearly a decade. Icahn and Catsimatidis belong to a group of 221 people who appear in the 1997 address book but not the later one.

Icahn made his fortune through investing in acquisitions, and gained notoriety in the 1980s for pursuing hostile takeovers of several companies, including the airline TWA. In 2017, Icahn served briefly as a special advisor to then-President Donald Trump on financial regulation, resigning hours before The New Yorker published an article on conflicts of interest created by Icahn's role.

Icahn's name is one of a handful that are highlighted in the book, although the precise meaning of the highlighting is unclear. A representative for Icahn declined to comment.

John Catsimatidis, who owns the Manhattan grocery chain Gristedes, told Insider that he met Epstein through his friend Evangeline Gouletas, a real estate executive who shared an office with Epstein in the building of the then-Helmsley Hotel in the early 1990s.

When they were introduced at Gouletas' office, Catsimatidis offered Epstein a ride on his upcoming weekend flight to Florida. Epstein later sent a three-foot bottle of champagne in thanks.

"That was the last time I saw him. He called me once or twice, I don't know what about," Catsimatidis said.
