Thierry Magon de La Villehuchet

Funds managed by Villehuchet enlisted intermediaries with links to some of Europe's high society to garner clients. The FBI and U.S. Securities and Exchange Commission (SEC) do not believe Villehuchet was involved personally in the US$50 billion fraudulent financial Ponzi scheme which Madoff was arrested for masterminding, on 11 December 2008. Bloomberg News reported on 2 January 2009 that the AIA funds had increased aggregate exposure to Madoff from 30% to 75% of a total US$3 billion assets in 2008, for a US$2.25 billion exposure. Investigators also identified a number of prominent investors who gave money to Villehuchet that was tied to the Madoff scandal: Philippe Junot, former husband of Princess Caroline of Monaco, and Prince Michael of Yugoslavia, as partner and investor-relations executive, respectively, in the firm; and Liliane Bettencourt, the world's wealthiest woman at the time (d. ⁠2017), the 86-year-old daughter of L'Oréal founder Eugène Schueller.

On 23 December 2008, Thierry Magon de La Villehuchet was found dead in his company office on Madison Avenue in New York City. He was 65. He was the first physical victim of the Madoff investment scandal. AIA Group had lost $1.5 billion, including his and Littaye's personal fortunes. He had been warned months earlier that Madoff might have been engaging in fraud, but dismissed this allegation. After Madoff's Ponzi scheme imploded, Villehuchet held out some hope he would be able to recover a portion of his money, but opted to take his own life when it was apparent it was all irretrievably lost. By 18 December, a week after Madoff's arrest, Villehuchet realised that he and AIA were finished. He had no means to pay his employees, and there were rumours of criminal charges in Europe. A friend told him, "Your professional life is over."

Bloomberg reported Bertrand had invested 20% of his assets in an AIA/Madoff fund and also reported René-Thierry had founded Access in 1994 with Littaye. The two had met at Paribas in 1970. In February 2009, Littaye denied having heard of whistleblower Harry Markopolos' accusations against Madoff in the years before the scandal broke, and said Madoff was "of course" exempted from the usual handwriting analysis (graphology) which was among the due diligence efforts AIA made with its outside fund managers. In his book, No One Would Listen, Markopolos recalled that he developed an alternative product to Madoff for his then-employer, Rampart Investment Management. In 2002, while touring Europe alongside de la Villehuchet to recruit potential investors, Markopolos recalled hearing managers from 14 separate funds claim that Madoff's investment advisory arm was "closed," but that their fund was the only source of new money for Madoff–a classic "robbing Peter to pay Paul" scenario.

In New York, Villehuchet was head of Interfinance, a brokerage firm, before becoming chairman and CEO of Crédit Lyonnais Securities USA in 1987. He also contributed to the founding of Apollo Management, financial management firm established by financier Leon Black.

René-Thierry Magon de La Villehuchet was born in Saint-Malo, into the Magon family, wealthy Breton shipbuilders. In 1978, he earned his MBA from HEC Paris. He moved to New York City in 1982.

René-Thierry Magon de La Villehuchet (23 April 1943 – 22 December 2008) was a French aristocrat, money manager, and businessman. He was one of the founders of Access International Advisors (AIA Group), a company caught and subsumed in the Madoff investment scandal in 2008. He killed himself after losing an estimated $1.4 billion in the Madoff scheme.
