30 Famous Polymaths (and the One Habit to Steal from Each)

The most famous polymaths in history include Aristotle, Ibn Sina, Leonardo da Vinci, Gottfried Leibniz, Benjamin Franklin, Alexander von Humboldt and Rabindranath Tagore. This list covers 30 of them across 2,400 years, including nine women and thinkers from China, Persia, Mexico, the Philippines and India. For each: dates, fields, one concrete achievement, and one habit you can copy this week.

In 17th-century Mexico, a teenage girl takes a pair of scissors and cuts off several inches of her hair. It is a deal with herself. If she has not mastered the subject she set by the time it grows back, she will cut it again, because a head so bare of knowledge does not deserve to be crowned with hair. The girl became Sor Juana Inés de la Cruz, the greatest poet of colonial Spanish America, and she told the story in a 1691 letter defending a woman's right to learn (La Respuesta a Sor Filotea).

Most lists of famous polymaths give you ten European men and an encyclopedia paragraph each. This one ends every entry with the habit to steal: one small practice that person used, which you can copy without being a genius. For the definition, read what a polymath actually is. For the plan, see our guide on how to become a polymath. This page is about the people.

List of polymaths at a glance

How we chose: each person did recognised work in at least two fields far apart (physics and poetry, not physics and chemistry). A hobby does not count. Einstein loved his violin, but he was a physicist who played music, not a polymath, which is why he is not here.

Ancient and medieval polymaths

Before universities split knowledge into departments, serious thinkers were expected to range widely. What stands out is how often they built things to test their ideas.

Aristotle (384-322 BCE)

Aristotle tutored the young Alexander the Great, founded the Lyceum in Athens, and wrote the first systematic works on logic, biology, ethics and politics. His biology is the forgotten part. He described how a male octopus uses a special arm to mate, a claim dismissed as absurd until 19th-century naturalists confirmed it (Britannica).

The habit to steal: sort before you theorise. Aristotle classified hundreds of animals before drawing conclusions. In a new subject, list its kinds and categories before reading anyone's grand theory.

Zhang Heng (78-139 CE)

Zhang Heng was chief astronomer to the Han court, and his poetry is still anthologised. In 132 CE he presented a bronze vessel ringed with eight dragons, each holding a ball above a waiting toad. Han records say a ball once dropped although nobody in the capital felt a thing. Days later a messenger reported an earthquake hundreds of kilometres away, in the direction the dragon had pointed.

The habit to steal: turn an idea into an object. Zhang did not argue that distant quakes could be detected; he built a device that proved it. Sketch, code or prototype one idea from whatever you are learning.

Hypatia (c. 350-415 CE)

Hypatia led the Neoplatonist school in Alexandria and was the leading mathematician and astronomer of her day, the earliest woman in mathematics whose life we know in any detail. She lectured publicly, and her student Synesius later wrote to her for help with scientific instruments. In March 415 she was murdered by a Christian mob during a political feud (Britannica).

The habit to steal: teach in public. Explaining a topic out loud, even to one friend, exposes the gaps in your understanding faster than rereading.

Al-Biruni (973-c. 1050)

Al-Biruni wrote on astronomy, mathematics, mineralogy, pharmacology and history. He learned Sanskrit to read Indian science in the original, then wrote a remarkably fair-minded study of India. From a mountain near Nandana, in today's Pakistan, he measured the dip of the horizon and calculated the Earth's radius at roughly 6,340 km, within about 1% of the modern value.

The habit to steal: go to the source. When a subject matters, read one original paper, book or dataset instead of a fifth summary of it.

Ibn Sina (Avicenna) (c. 980-1037)

Ibn Sina wrote the Canon of Medicine, taught in European medical schools for centuries, and The Book of Healing, a vast encyclopedia of philosophy and science. In his autobiography he says he read Aristotle's Metaphysics forty times, memorised it and still did not understand it, until a bookseller sold him al-Farabi's short commentary for three dirhams (Internet Encyclopedia of Philosophy). Scholars suspect "forty" just means "many". The lesson stands.

The habit to steal: when you are stuck, change the guide, not the effort. If a book defeats you after honest work, find a different explainer.

Shen Kuo (1031-1095)

Shen Kuo was a Song dynasty official, general, astronomer and engineer. His Dream Pool Essays (1088), a sprawling notebook on everything from music to fossils, give the earliest known description of a magnetic needle compass and note that the needle points slightly off true south, the first recorded observation of magnetic declination.

The habit to steal: keep one notebook for everything. When all your curiosities sit side by side, cross-connections happen by themselves.

Hildegard of Bingen (1098-1179)

Hildegard, a Benedictine abbess, composed some of the most distinctive music of the Middle Ages, wrote on medicine and natural history, and invented a private language of about a thousand words. Her sung drama Ordo Virtutum (around 1151) is the oldest surviving morality play by more than a century. She began her major visionary book, Scivias, at 42.

The habit to steal: start late anyway. Almost everything Hildegard is remembered for came after 40.

Renaissance and early modern polymaths

This era gave us the phrase "Renaissance man" (see our post on the Renaissance man meaning). It is also when women start appearing in the record despite every effort to keep them out.

Leon Battista Alberti (1404-1472)

Alberti designed the upper façade of Santa Maria Novella in Florence, wrote plays and dialogues, and in De pictura (1435) set down the first theory of linear perspective for painters. Around 1467 he described a cipher disk of two rotating alphabets, the first polyalphabetic cipher, which is why he is often called the father of Western cryptography.

The habit to steal: write the manual. After learning something, write a one-page guide for a beginner. You will see exactly what you understood.

Leonardo da Vinci (1452-1519)

Leonardo painted the Mona Lisa, dissected human bodies, designed machines and studied water, rock and flight. More than 7,000 pages of his notebooks survive. On one to-do list, between chores, he wrote: "Describe the tongue of the woodpecker." Walter Isaacson built his biography around that line. Two myths to drop: no contemporary source says he slept 20 minutes every four hours, and "Simplicity is the ultimate sophistication" has never been found in his writings (Quote Investigator).

The habit to steal: keep a curiosity list. Start a note called "Things I want to know", add one question a day, and answer one a week.

Gottfried Wilhelm Leibniz (1646-1716)

Leibniz invented calculus independently of Newton (we still use his ∫ and dx), developed binary arithmetic, built a calculating machine that could multiply, and worked as a lawyer, diplomat and librarian. His surviving correspondence runs to about 15,000 letters with some 1,100 people, from Europe to China, and sits in UNESCO's Memory of the World register (UNESCO).

The habit to steal: write to people who know more than you. Send one thoughtful question a month to an author or researcher you admire. Many will answer.

Maria Sibylla Merian (1647-1717)

When many Europeans still believed insects sprang from mud, Merian raised caterpillars and painted every stage of their change alongside the plants they ate. In 1699, at 52, she sailed to Suriname with her daughter Dorothea on a self-funded research trip. Her Metamorphosis Insectorum Surinamensium (1705) changed how naturalists saw insects (Natural History Museum).

The habit to steal: draw what you study. Even a bad sketch forces you to look at what is really there.

Sor Juana Inés de la Cruz (c. 1648-1695)

Sor Juana (born 1648 or 1651) entered a convent in Mexico City partly because it let her keep studying. She wrote poetry, plays and music, studied science and theology, and built one of the largest private libraries in New Spain. Her 1691 letter with the hair-cutting story is often called one of the first feminist manifestos in the Americas. Church pressure later forced her to give up her books.

The habit to steal: give your learning a deadline and a stake. Pick a subject, set a date, and attach something real to it: a promised talk, a bet with a friend, a public post.

Émilie du Châtelet (1706-1749)

Du Châtelet was a mathematician and physicist who championed the idea that led to modern kinetic energy. Her great project was a French translation of Newton's Principia with her own commentary, finished shortly before she died in 1749, days after giving birth. Published in full in 1759, it is still the standard French translation (MacTutor).

The habit to steal: translate to understand. Once a week, rewrite one dense page in plain language, sentence by sentence.

18th and 19th century polymaths

Science was turning professional and journals were multiplying. These were among the last people to try to follow nearly all of it, and several were women who had to learn in secret.

Benjamin Franklin (1706-1790)

Franklin was a printer, bestselling writer, the scientist who showed lightning is electricity, the inventor of the lightning rod, and a founding diplomat. In 1727, at 21, he started the Junto, a Friday-night "club of mutual improvement" for Philadelphia tradesmen. Each member brought questions to debate and read an essay of his own every three months. It seeded a lending library, a fire company and more (Encyclopedia of Greater Philadelphia).

The habit to steal: start a Junto. Find three to five curious people, meet every other week, and have each bring one question.

Mikhail Lomonosov (1711-1765)

A fisherman's son from the White Sea, Lomonosov walked with a trading caravan to Moscow in the winter of 1730 to get an education. He became a chemist, physicist, poet and grammarian, revived mosaic art in Russia, and helped found Moscow State University in 1755. Watching the 1761 transit of Venus, he saw a bright rim around the planet and concluded it has an atmosphere.

The habit to steal: go where the teachers are. Seek out the best course, lecture or mentor in your field, not the nearest one.

Johann Wolfgang von Goethe (1749-1832)

Goethe wrote Faust, served as a minister in the duchy of Weimar, studied plant form, and published a Theory of Colours (1810) he considered his most important work. In 1784 he showed that humans have an intermaxillary bone, though French anatomists had described it a few years earlier. His colour theory shows the polymath's risk: on the physics, Newton was right and Goethe was wrong, even if his notes on how we perceive colour still interest artists.

The habit to steal: bring fresh eyes to a science, then check your conclusions with specialists. Outsiders spot what experts miss, and also make confident mistakes.

Alexander von Humboldt (1769-1859)

Humboldt spent 1799 to 1804 exploring Latin America with the botanist Aimé Bonpland. In 1802 they climbed Chimborazo in Ecuador to around 5,900 metres, higher than anyone was known to have climbed. On the way down he began his Naturgemälde, one picture of the mountain showing which plants grow at which altitude, with temperature and air pressure alongside: nature drawn as a connected system.

The habit to steal: draw the connections. Once a month, put everything you are learning on one page and draw lines between the topics.

Thomas Young (1773-1829)

Young was a practising physician who showed with his double-slit experiment that light behaves like a wave, gave his name to Young's modulus, proposed a three-colour theory of vision, and made the first real progress on the Rosetta Stone. He also wrote 63 articles for the Encyclopaedia Britannica. His biographer Andrew Robinson called him The Last Man Who Knew Everything.

The habit to steal: write short explainers. A 300-word summary of a topic you just learned keeps it fresh for years.

Mary Somerville (1780-1872)

Somerville first saw algebra in a puzzle in a women's fashion magazine and asked what the x's and y's meant. Her father forbade her to study mathematics, so she studied at night. Her 1834 On the Connexion of the Physical Sciences became a bestseller. Contrary to a popular story, the word "scientist" was not coined for her, but it first appeared in print in William Whewell's review of that book.

The habit to steal: chase the symbol you do not understand. When a word or symbol stops you, look it up right then.

Ada Lovelace (1815-1852)

In 1843 Lovelace translated an article on Charles Babbage's Analytical Engine and added seven notes about three times longer than the article. Note G sets out steps for the machine to compute Bernoulli numbers, often called the first published computer program. She also saw that such a machine could work with symbols and might compose music if harmony were expressed in its terms. She called this "poetical science" and signed the notes only A.A.L.

The habit to steal: ask what else a tool could do. Take one tool you use daily and list three uses nobody intended.

José Rizal (1861-1896)

Rizal trained as an eye surgeon partly to treat his mother, and later removed her cataracts himself. His novel Noli Me Tángere (Berlin, 1887) exposed colonial abuse and fed the Philippine independence movement. He also sculpted, wrote poetry and collected specimens; a flying lizard, Draco rizali, is named after him. Claims that he knew 22 languages deserve caution. Spanish authorities executed him in 1896, at 35.

The habit to steal: let a real problem choose your next field. Ask what problem in your life a new skill would solve, and learn that.

20th century: the modern polymaths

After 1900 nobody could reach the front edge of every field. The modern polymaths below combined a few fields instead, often against racism, blacklisting or sexism.

Rabindranath Tagore (1861-1941)

In 1913 Tagore became the first non-European to win the Nobel Prize in Literature. He wrote more than 2,000 songs, including the national anthems of both India and Bangladesh, plus novels and plays, and founded a university, Visva-Bharati. In his sixties he started painting, partly by turning the crossed-out words in his manuscripts into figures, and went on to make more than 2,000 paintings and drawings.

The habit to steal: play in the margins. Let one playful side project live next to your serious work.

W.E.B. Du Bois (1868-1963)

Du Bois was the first African American to earn a Harvard PhD (1895), wrote the pioneering study The Philadelphia Negro (1899), co-founded the NAACP, edited The Crisis and wrote novels. For the 1900 Paris Exposition, he and his Atlanta University students hand-drew more than 60 charts on Black life in America. With their bold colours and spirals they look strikingly modern, and the Library of Congress holds them.

The habit to steal: turn your numbers into a picture. Before you share a statistic that matters, sketch it as a chart.

Paul Robeson (1898-1976)

Robeson was valedictorian at Rutgers and twice a consensus All-American in football. He earned a Columbia law degree while playing in the early NFL, then became one of the most famous singers and actors of his era; his 1943 Broadway Othello set a record run for Shakespeare on Broadway. His politics cost him: the US government revoked his passport from 1950 to 1958.

The habit to steal: let one field fund the next. Ask which of your current skills could pay, in money or time, for the next one.

John von Neumann (1903-1957)

Von Neumann gave quantum mechanics a rigorous mathematical footing, co-wrote Theory of Games and Economic Behavior (1944) with Oskar Morgenstern, founding game theory, and in 1945 wrote the report describing the stored-program design most computers still follow. He liked noise; Princeton colleagues complained about German marching music blasting from his office.

The habit to steal: take your best tool on tour. Apply whatever you are good at, whether statistics, drawing or negotiation, to a field that rarely uses it.

Hedy Lamarr (1914-2000)

Hedy Lamarr was an MGM star and a self-taught inventor. In 1942 she and the composer George Antheil received US patent 2,292,387 for a radio signal that hopped between 88 frequencies, synchronised like two player-piano rolls, so it could not be jammed. The claim that she "invented Wi-Fi" goes too far: spread-spectrum ideas predate her, and later systems were built independently (American Scientist). But the patent was real, clever and hers.

The habit to steal: find a collaborator from a distant field. Lamarr brought the problem; a composer brought the mechanism.

Herbert Simon (1916-2001)

Simon won the Turing Award in 1975 (with Allen Newell) for work on artificial intelligence and the psychology of thinking, then the Nobel Prize in Economics in 1978 for research on decision-making in organisations (Nobel Prize). He also coined "satisficing": choosing the option that is good enough instead of searching forever for the best.

The habit to steal: satisfice outside your core. Aim for excellence in one or two things and "good enough to talk to the experts" in the rest.

Polymaths alive today

The label gets thrown around loosely, especially at tech founders with busy side projects. Running companies in several industries is not the same as contributing to several fields of knowledge, so treat that coverage with caution. These three have recognised work in fields far apart.

Jared Diamond (born 1937)

Diamond earned a PhD in physiology in 1961 and became a professor of physiology at UCLA's medical school. From 1964 he also worked as an ornithologist in New Guinea, and in his fifties he became a professor of geography. Guns, Germs, and Steel won the 1998 Pulitzer Prize, though many anthropologists criticise it for leaning too hard on geography. He published a new book on leadership in September 2026.

The habit to steal: switch fields in chapters. Go deep for several years, then carry your methods into the next field.

Brian May (born 1947)

As Queen's guitarist, May wrote "We Will Rock You" on a guitar he built with his father as a teenager, using mahogany from an old fireplace. He had nearly finished a PhD in astrophysics when Queen took off. More than 30 years later he went back, and Imperial College London awarded his doctorate in 2007 for a thesis on dust in the solar system (Imperial College). He is also a devoted maker of stereoscopic 3D photographs.

The habit to steal: go back and finish the thing you dropped. Give the abandoned course, instrument or language one more honest month.

Mae Jemison (born 1956)

Jemison studied chemical engineering at Stanford while also completing a degree in African and African American studies, then qualified as a doctor at Cornell. She served as a Peace Corps medical officer in Sierra Leone and Liberia, and on 12 September 1992 became the first African American woman in space, aboard the shuttle Endeavour. She is also a trained dancer.

The habit to steal: refuse the either-or. If you were told to choose between a creative interest and a technical one, keep both.

Female polymaths: the ones history tried to skip

Nine of the thirty people here are women, and each got around a wall the men never faced. Hypatia was killed in a political riot. Sor Juana was pressured to give up her library. Maria Sibylla Merian paid for her own expedition. Émilie du Châtelet was published in full only after her death. Mary Somerville studied mathematics against her father's orders. Ada Lovelace signed with initials. Hedy Lamarr was valued for her face while her patent sat unused. Hildegard and Mae Jemison worked inside institutions built mostly by and for men.

Women were not less often polymaths. The record was built to leave them out, so the famous female polymaths we know are the ones too productive to ignore.

Who was the greatest polymath in history?

There is no objective answer, because it depends on what you measure. The usual candidates:

• Aristotle for influence. His logic and biology shaped learning in Europe and the Islamic world for nearly 2,000 years.
• Leonardo da Vinci for range of curiosity, though he finished relatively few projects.
• Ibn Sina or Leibniz for first-rate work in several fields at once.
• Thomas Young or Humboldt as the last who could follow most of science. The title "the last man who knew everything" has been pinned on Young, Leibniz and the Jesuit scholar Athanasius Kircher, which says more about our love of the idea than about any of them.

The better question is what these people did that you can do too.

What famous polymaths had in common

Read thirty lives in a row and the same habits keep turning up. None requires genius.

They wrote things down. Leonardo's lists, Shen Kuo's essays, Leibniz's letters and Young's encyclopedia entries were all thinking on paper.

They went deep, one field at a time. Hildegard began her major writing at 42, Merian sailed to Suriname at 52, Tagore started painting in his sixties, and Diamond switched fields in his fifties. Breadth came from a series of deep dives, not constant skimming. If you fear becoming a jack of all trades, master of none, the full version of that saying is kinder than the short one.

They borrowed methods. Alberti brought geometry to painting, Du Bois brought design to sociology, von Neumann brought mathematics to economics.

They had people. Franklin had his Junto, Leibniz his 1,100 correspondents, Lamarr her Antheil.

Modern evidence points the same way. Nobel laureates in science are significantly more likely than other scientists, or the general public, to have serious arts and crafts hobbies such as painting, music or woodwork (Root-Bernstein et al., 2008). It is a correlation, not proof, but it fits. For the wider debate, see generalist vs specialist, and if restless interests sound like you, read about the multipotentialite.

You do not need to be Leonardo

Nobody here started famous. Sor Juana started with scissors and a deadline. Somerville started with a magazine puzzle. Franklin started with a dozen tradesmen in a tavern. Pick one habit from this page and try it for a month.

When you want to build a routine around it, our guide to becoming a polymath in real life has the full plan and the best learning sources, from university courses and MOOCs to books and podcasts. For daily breadth, a short course on a topic you would never have picked helps; NerdSip's Polymath Sampler is a five-minute way to start, with a quiz after every lesson.

Every NerdSip course clears a four-layer fact-checking pipeline before it reaches the app: grounded in live sources, scored nightly, gated on failure, and reviewable by a person at one tap. Articles on this blog are drafted with AI assistance, then researched, verified, and edited by our team.
