I have just finished reading the FT’s excellent recent story on Gérard Lhéritier, the French manuscript dealer who raised a $1 billion fund based on selling shares in priceless literary artefacts — before the whole thing was unravelled as an (allegedly) fraudulent Ponzi scheme in 2025. What was notable about Lhéritier (besides the strange footnote that he also won France’s biggest ever EuroMillions jackpot in 2007) was how much of a fixture of polite Parisian society he was: a well-tailored, patrician presence who was a respected sponsor of the National Library of France. It reminded me of something a friend who works in finance once explained to me: that a good proportion (maybe even the majority) of Ponzi schemes go entirely undetected. That, statistically speaking, at least a few of the most respected financiers and fund managers in the game must surely at some point have employed Ponzi-esque practices — taking from Peter to pay Paul, essentially — before landing the plane at the last minute and legitimising their business entirely. When you put it like that, it can sound almost acceptable — just another ‘fake it till you make it’ element of our modern hustle culture. (And besides, ‘Ponzi’ sounds so chic and Italianate. “Oh, this tie? It’s vintage Ponzi…” ) But setting up a Ponzi scheme is the easy bit. You promise handsome returns, and foolhardy investors give you their money accordingly, and then you pay them out based on the deposits of further, later foolhardy investors, and the wheel turns. The problem, of course, is getting out. Here are five of the most notable fraudsters who didn’t.
