Abstract

Thérèse Humbert was a lowly French peasant until she saved the life of an American millionaire who left her a vast inheritance, but after twenty years of litigation over said inheritance, a massive web of deception unraveled. The millionaire had never existed, his “nephews” were actually Humbert’s brothers, and Humbert herself had swindled Europe’s moneyed men and working-class laborers out of millions of francs. Overnight, Humbert became a celebrity in the American press, even after she was convicted and imprisoned for fraud. The French swindler’s onslaught of coverage in American newspapers shaped Gilded Age anxieties about money, credit, and the place of women in an ever-changing world. Gender ideologies concerning women’s place in the economy and turn-of-the-century financial instability made the Humbert swindle irresistible to the American press, who saw the story as an opportunity to moralize about women and finance. The sheer scale of Humbert’s fraud and its American coverage make the story remarkable today as an astonishing episode in the Gilded Age and Progressive Era, especially among cultural historians and those interested in the New History of Capitalism.

Figure 1. Madame Thérèse (D’Aurignac) Humbert, depicted in the Washington, D.C. Evening Star, January 1, 1903. She was said to have borrowed hundreds of millions of francs from financiers and banks all across France, as well as stealing from the retirement funds of working-class Parisians.

Figure 2. A crowd awaits the opening of the Humbert safe on the Avenue de la Grande Armée. This detailed illustration appeared in a Harper’s Weekly feature about Humbert, dated January 10, 1914. Sources from the period vary in their details about the opening of the safe. Some suggest that lawyers and creditors were inside the mansion, opening the safe at its typical location, only to find it empty. Others, including this Harper’s Weekly article, say that the safe was lowered onto the street while a “jeering Paris crowd” observed the opening. The details of its contents, too, vary from source to source; some say it was utterly empty, others that it contained naught but a belt buckle; others a few coins; still others a brick. The variation in the historical record notwithstanding, most sources agree that the opening of the safe was an earth-shattering revelation that upended French financial markets and exposed the Humbert scheme for its fraudulence.

Figure 3. The whole family (clockwise from top right): Thérèse, her husband Frédéric, brother Emile, brother Romain, and daughter Eve. Many papers in the United States reproduced photographs or other depictions of Humbert and her family throughout the trial. Some articles about the scam would fill an entire broadsheet, while others would appear as brief blips under “Foreign News” sections. Her portrait was well-known to American readers whose newspapers continually reported on the trial. This photographic spread appeared in the Northern Wisconsin Advertiser, August 20, 1903.

Figure 4. “The guests were entertained thus lavishly in the hope of exploiting or of compromising them,” read the caption on this illustration showing Thérèse in her “ultra-salon,” surrounded by Parisian elites who are depicted subserviently at her beck and call. This illustration also vivifies Humbert’s supposed taste in clothing, wearing an extravagant ensemble that only a wealthy Parisian heiress could afford. Her sumptuous soirées were reputed to have attracted scholars, politicians, moneyed men, and famous cultural figures, all of whom ostensibly added to her reputation and social capital. It was this reputation on which she occasionally relied to garner more credit or stave off leery lenders expecting a payment. This illustration appeared in Harper’s Weekly, January 10, 1914.

Figure 5. “The Fund Cannot Be Touched.” The French court’s “contract of sequestration” required that the safe remain locked, and this gave the Humberts legal pretext to borrow against the fortune without ever having to open the safe or distribute any funds. The term is foreign to contemporary American jurisprudence, but the concept of sequestration essentially meant something comparable to freezing Humbert’s assets. She was technically in possession of the fortune and even had a legal standing to say that she “owned” the inheritance, but was legally barred from touching or spending any of that money under penalty of forfeiture. This gave her both the financial backing to hypothetically repay the loans, but also a plausible reason for why, if she really had this fortune sitting in her safe, she would need to borrow in the first place. This artist’s depiction appeared in the Evening Star, May 24, 1902.

Figure 6. This illustration, appearing in the Evening Star, May 24, 1902, purports to show Humbert bribing a bank manager with 900,000 francs, presumably to persuade him to lend her more money. Commentators on the case during the trial were not blind to the motivation for lending her money: her enormous loans promised massive sums back in interest. They trusted her, moreover, because she had political clout and an apparent fortune locked away in her wax-sealed safe. If all else failed, she could appeal to her connections to the French minister of justice, Gustave Humbert, who happened to be her father-in-law. Although the sources vary on whether Minister Humbert was personally involved with securing loans or intervening politically on Thérèse’s behalf – with some sources bordering on wild, unfounded speculation in their accusations of the same – it is clear from the majority of sources that Thérèse herself frequently invoked his name to calm concerned creditors.

Figure 7. “Fat, fair, and forty,” “stoutness,” “obesity,” and “ample waist” were descriptors used to denigrate Humbert after her scam was discovered. These labels played on a notion of degenerate people’s misdeeds being reflected in their weight. Humbert herself was never seen as having a “degenerate” body in the twenty years before her scam was exposed, showing the shortcomings in degeneration theory’s “reading” of criminal bodies as markers of vice. This photograph was reproduced in The Kalispell(Montana) Bee, December 22, 1903.

Figure 8. Pictorial representations of Humbert often accompanied stories about her, such as this one from the Chicago Daily Tribune on May 26, 1902. Humbert was widely reputed to have expensive taste in “fineries,” including jewelry, clothing, and hats. The diamond merchants of Paris not only ostensibly lent her money, but also were said to have sold her jewels that she wore and later pawned for more money. Some depictions, like this one, featured her in elaborate attire to illustrate her supposed exquisite wealth and luxury, while others focused on her physiognomy as a source of moral commentary.

Figure 9. The Humberts’ daughter was variously reported to be named either Eve or Eva. Although many sources reported that she was in fact a girl, others made Eve’s gender the subject of some speculation. The roles of Humbert’s family in general, including her husband, daughter, and her father-in-law, are debated in various publications. Her father-in-law, the French minister of justice Gustave Humbert, was accused by some of politically intervening to obstruct the investigation into Thérèse’s financial conduct. Her husband Frédéric is largely depicted as a gaunt man with artistic talent but limited intelligence. Her daughter, however, was scandalously depicted by some as a boy who “passed” or posed as a girl in order to seduce wealthy men with the promise of sex in order to secure more money in loans for the mother. The mendaciousness of this charge is almost too outlandish for comment, but it does suggest the power of Humbert’s story and the strength with which it gripped the moral imaginations of readers. This depiction of Eve appeared in an issue of the Rice Belt Journal, January 9, 1903.

Figure 10. This side-by-side of Humbert and her safe illustrates the way that some editors and reporters used Humbert’s swindle to moralize about women, crime, and the fleeting nature of fortune. On the left is a depiction of the safe being opened, this time apparently being inside her mansion as opposed to on the street. On the right, a “study” of Humbert herself. The interstices feature comical bags of money flying away. This illustrated the moral of the story: she had swindled all this money, but it proved to be ethereal (for her lenders and herself). This panel appeared in the Topeka State Journal, February 6, 1903.
