Criminal Geniuses: 34 Brilliant Minds Who Broke the Law

From Caravaggio to the Unabomber: painters, poets, physicists and programmers whose genius was real, and whose crimes were too.

Genius does not come with a conscience attached. History's record of brilliant minds includes a prince who murdered his wife and wrote the strangest music of the Renaissance, a physicist who passed the secrets of the atomic bomb to Stalin, a philologist hanged for a killing he hid for thirteen years, and a Harvard mathematician who mailed bombs for seventeen. This is the full list we could verify: 34 people whose talent was real and whose crimes were too.

Caravaggio, David with the Head of Goliath (about 1610), painted while he was a fugitive from a death sentence for murder. The severed head is widely read as his self-portrait. Galleria Borghese, Rome. Public domain.

How we chose them

Two tests, both strict. First, proven genius: a documented achievement in a field, such as paintings in the great museums, music still performed, physics that built the bomb, software that ran on millions of machines. Where criminal skill is the whole story, as with the forgers, the hackers and the four masters of the con, the skill itself had to be extraordinary and documented. Second, a real crime: a conviction, or a crime that the historical record establishes beyond doubt.

We left out people convicted under unjust laws: Socrates, Galileo, Oscar Wilde, Alan Turing, and the writers jailed for their politics. A sentence for heresy, for love or for dissent says more about the court than about the defendant. We also left out the Nazi leadership and mass murderers, whose crimes no achievement can frame, and sexual crimes against children. Frank Abagnale is missing because most of his famous story has been shown to be invented.

Murder and violence

• Carlo Gesualdo (1566–1613), composer. In October 1590, in Naples, he killed his wife, Maria d'Avalos, and her lover, Fabrizio Carafa. As a prince he was never tried. His late madrigals, chromatic and unsettling, still sound modern four centuries on.
• Benvenuto Cellini (1500–1571), goldsmith and sculptor. Cast the bronze Perseus with the Head of Medusa in Florence. He killed at least three men; Pope Paul III pardoned him for the 1534 killing of the goldsmith Pompeo de' Capitaneis in Rome.
• Caravaggio (1571–1610), painter. Rewrote European painting with violent light and street-level realism. In May 1606 he killed Ranuccio Tomassoni in a fight in Rome, was sentenced to death in his absence, and spent his last four years on the run through Naples, Malta and Sicily.
• François Villon (about 1431–after 1463), poet. The greatest French poet of the late Middle Ages killed a priest in a street brawl in 1455 and joined a burglary of the Collège de Navarre in 1456. In 1463 a death sentence was commuted to ten years' banishment from Paris. Then he vanished.
• Eugene Aram (1704–1759), philologist. Taught himself Latin, Greek, Hebrew and the Celtic languages and saw that Celtic belongs to the same family as the other great European languages. Hanged at York in 1759 for the murder of the shoemaker Daniel Clark in 1745.
• Richard Dadd (1817–1886), painter. In 1843, during a psychotic breakdown, he killed his father. He spent the rest of his life, more than four decades, in Bethlem and Broadmoor hospitals, where he painted The Fairy Feller's Master-Stroke.
• William Chester Minor (1834–1920), army surgeon. In 1872, in the grip of paranoid delusions, he shot and killed George Merrett in London. Found not guilty by reason of insanity, he sent thousands of quotations from Broadmoor to the first Oxford English Dictionary.
• Paul Verlaine (1844–1896), poet. In July 1873, in a Brussels hotel room, he fired two pistol shots at Arthur Rimbaud and wounded him in the wrist. A Belgian court sentenced him to two years in prison.
• Lead Belly (about 1888–1949), musician. The twelve-string master behind "Goodnight, Irene" served time in Texas for killing a man and in Louisiana for assault with intent to murder. Texas pardoned him in 1925 after hearing him sing.
• Leopold and Loeb: Nathan Leopold (1904–1971) and Richard Loeb (1905–1936), two wealthy, precocious Chicago university graduates still in their teens. In May 1924 they kidnapped and murdered 14-year-old Bobby Franks to prove they could commit a perfect crime. Clarence Darrow saved them from execution.
• William S. Burroughs (1914–1997), novelist. The author of Naked Lunch shot and killed his wife, Joan Vollmer, in Mexico City in September 1951.
• Louis Althusser (1918–1990), philosopher. In November 1980 he strangled his wife, the sociologist Hélène Rytmann, in their Paris apartment. Declared not criminally responsible, he was never tried.
• Phil Spector (1939–2021), record producer. Built the Wall of Sound and remade 1960s pop. Convicted in 2009 of the second-degree murder of the actress Lana Clarkson; he died in prison.
• Ted Kaczynski (1942–2023), mathematician. Harvard at 16 and Berkeley at 25; then, as the Unabomber, 16 bombs between 1978 and 1995 that killed three people and injured 23.
• Mark Hofmann (born 1954), document forger. His fake Mormon and early American documents fooled leading experts. To cover his tracks he killed Steven Christensen and Kathleen Sheets with bombs in 1985; he pleaded guilty and is serving life in Utah.
• Hans Reiser (born 1963), programmer. Entered Berkeley at 15 and created the ReiserFS file system for Linux. Convicted in 2008 of murdering his wife, Nina Reiser; he remains in California state custody.

Espionage

• Klaus Fuchs (1911–1988), theoretical physicist. Worked on the first atomic bombs at Los Alamos and passed their secrets to the Soviet Union. Convicted in London in 1950.
• Alan Nunn May (1911–2003), nuclear physicist. On the wartime Anglo-Canadian atomic project he handed uranium samples and secret reports to Soviet intelligence. Convicted in 1946 and sentenced to ten years.

Forgery

• Thomas Griffiths Wainewright (1794–1847), painter and critic. Forged his way into his own trust fund and was transported to Tasmania in 1837. He was suspected, never tried, of poisoning three relatives.
• Han van Meegeren (1889–1947), painter. Faked Vermeers good enough to fool the experts and sold one to Hermann Göring. Convicted of forgery and fraud in 1947 and sentenced to one year; he died before serving it.
• Elmyr de Hory (1906–1976), painter. Could pass for Picasso, Matisse and Modigliani and put an estimated 1,000 forgeries on the market. He was never convicted of forgery, but he admitted the fakes in Clifford Irving's Fake! (1969), and France was seeking his extradition for fraud when he died in 1976. Orson Welles made him the star of F for Fake.
• Wolfgang Beltracchi (born 1951), painter. Invented "lost" works by Max Ernst, Heinrich Campendonk and others that fooled leading experts. Convicted of commercial gang fraud in Cologne in 2011 and sentenced to six years.

Fraud, theft and bribery

• Francis Bacon (1561–1626), philosopher and Lord Chancellor of England. Laid the foundations of the scientific method. In 1621 he admitted taking gifts from parties in cases before him, was fined £40,000 and was briefly held in the Tower of London.
• O. Henry (1862–1910), short-story writer. Convicted in 1898 of embezzling from a bank in Austin, Texas, he served three years in the Ohio Penitentiary and published stories under the pen name that hid his record.
• Jean Genet (1910–1986), novelist and playwright. A career thief who wrote his first novels in prison. Facing life imprisonment as a repeat offender, he was pardoned in 1949 after writers led by Jean Cocteau and Jean-Paul Sartre appealed for him.
• Bernie Madoff (1938–2021), financier. A pioneer of electronic market-making and three-time chairman of Nasdaq, he ran the largest Ponzi scheme in history. Pleaded guilty to 11 felonies in 2009 and was sentenced to 150 years.
• Sam Bankman-Fried (born 1992), financier. An MIT physics graduate who built the crypto exchange FTX into a $32 billion business, then was convicted in 2023 of defrauding its customers and sentenced to 25 years.

Computer crime

• Kevin Mitnick (1963–2023), hacker. Spent two and a half years on the run from the FBI, was arrested in 1995 and served five years in prison, then rebuilt himself as a security consultant.
• Robert Tappan Morris (born 1965), computer scientist. His 1988 Morris worm crippled a large share of the early internet; in 1990 he became one of the first people convicted under the Computer Fraud and Abuse Act. He became an MIT professor and co-founded Y Combinator.

The masters of the con

• Adam Worth (about 1844–1902). Ran a transatlantic theft and forgery syndicate as "Henry Raymond" and stole Gainsborough's portrait of the Duchess of Devonshire in 1876. Scotland Yard called him the Napoleon of the criminal world, and he is often cited as an inspiration for Professor Moriarty.
• Charles Ponzi (1882–1949). His 1920 Boston postal-coupon scheme drew some 30,000 investors and gave fraud his name. He pleaded guilty to mail fraud and died poor in Rio de Janeiro.
• Victor Lustig (1890–1947). Famed for "selling" the Eiffel Tower in 1925, a story that rests largely on later accounts. His proven crimes were counterfeiting and a 1935 jailbreak; he died in federal custody.
• Ferdinand Waldo Demara (1921–1982). With no medical training, he posed as a Royal Canadian Navy surgeon in the Korean War and operated on wounded men. Hollywood made him The Great Impostor, with Tony Curtis.

What the list teaches

Read the 34 lives together and one pattern stands out: intelligence explains the method, never the motive. It let Kaczynski evade the FBI for seventeen years, let van Meegeren fool the experts, let Madoff run his fraud for decades. It did not make any of them better people, and it shortened none of their victims' grief. The talent belongs in the record. So does the crime.

Frequently Asked Questions

Who is the most famous criminal genius in history?

Caravaggio is the strongest case of world-class talent combined with a proven killing: he killed Ranuccio Tomassoni in Rome in 1606 and spent the rest of his life as a fugitive. For a crime planned with intelligence, the Unabomber, the former Berkeley mathematician Ted Kaczynski, is the best-known modern example.

Which famous scientists were spies?

Klaus Fuchs, a theoretical physicist at Los Alamos, passed atomic bomb secrets to the Soviet Union and was convicted in London in 1950. Alan Nunn May, a British nuclear physicist, was convicted in 1946 of handing uranium samples and secret reports to Soviet intelligence.

Which great artists killed someone?

Caravaggio (1606), Benvenuto Cellini (at least three men, between about 1530 and 1540), the composer Carlo Gesualdo (1590), the painter Richard Dadd (1843) and the producer Phil Spector (convicted in 2009). The poet Paul Verlaine shot and wounded Arthur Rimbaud in 1873.

Did anyone really sell the Eiffel Tower?

The story of Victor Lustig "selling" the Eiffel Tower for scrap in 1925 rests largely on later accounts, and the details differ between them. What is proven is that he was a counterfeiter, escaped from jail in 1935 and died in federal custody in 1947.

Why is Alan Turing not on this list?

Turing was convicted in 1952 of "gross indecency" for a relationship with another man, under a law Britain later repealed. The government apologized for his treatment in 2009, and he received a royal pardon in 2013. We count crimes, not punishments for who someone loved.
