21 Famous Polymaths and What They Mastered

The most famous polymaths include Aristotle, Ibn Sina, Leonardo da Vinci, Leibniz, Benjamin Franklin, Alexander von Humboldt, Rabindranath Tagore and, closer to our time, Mae Jemison. This list covers 21 people from 2,400 years, across Greece, Egypt, Central Asia, China, Europe, Mexico, India, the United States and Britain. Each entry gives dates, their fields and one achievement checked against an encyclopedia or primary source.

If you want the definition first, read what a polymath is. This page is about the people. We also left out some names you may expect. Einstein, for example, was a great physicist, but a serious hobby is not the same as recognized work in a second field.

Who Are the Most Famous Polymaths in History?

The best-known polymaths are Aristotle, Leonardo da Vinci, Ibn Sina, Leibniz, Benjamin Franklin and Alexander von Humboldt. The table lists all 21 in date order. Fields are summarized from the sources at the end of the page.

Which Ancient and Medieval Polymaths Are Best Known?

Six stand out: Aristotle, Hypatia, Ibn al-Haytham, Al-Biruni, Ibn Sina and Shen Kuo. Before universities split knowledge into departments, wide learning was normal for serious scholars.

Aristotle (384 to 322 BCE). Britannica describes him as an ancient Greek philosopher and scientist. He tutored Philip II's son Alexander for two or three years and then set up his own school, the Lyceum, where many lectures were open to the public and given free of charge.

Hypatia (c. 355 to 415). A mathematician, astronomer and philosopher in Alexandria. Britannica calls her the earliest female mathematician of whose life and work reasonably detailed knowledge exists. She died in March 415, in a turbulent period for the city.

Ibn al-Haytham (c. 965 to 1040). Born in Basra, he wrote an Optics that offered a correct model of vision and championed the use of scientific experiments.

Al-Biruni (973 to c. 1052). Born in Khwarezm, in what is now Uzbekistan, he is described by Britannica as an astronomer, mathematician, ethnographer, anthropologist, historian and geographer. His writing on Indian culture, science, religion and customs earned him fame as a historian of Indian science.

Ibn Sina, or Avicenna (980 to 1037). Born near Bukhara. His Canon of Medicine served as a textbook in Europe until the mid-17th century, and his Book of the Cure was a vast philosophical and scientific encyclopedia.

Shen Kuo (1031 to 1095). A Chinese astronomer, mathematician and high official. His notebook, the Mengxi bitan, contains the first reference to the magnetic compass, the first description of movable type and a fairly accurate explanation of the origin of fossils, alongside notes on optics, cartography and medicine.

Which Renaissance and Early Modern Polymaths Should You Know?

Leonardo da Vinci, Leibniz, Maria Sibylla Merian and Sor Juana Inés de la Cruz. This era gave us the phrase "Renaissance man," and it is also when women appear more often in the record of science and letters.

Leonardo da Vinci (1452 to 1519). Britannica calls him a painter, draftsman, sculptor, architect and engineer. He never published his scientific studies, so his student Melzi inherited more than 10,000 pages of notes, the most voluminous literary legacy any painter had left behind.

Gottfried Wilhelm Leibniz (1646 to 1716). The Stanford Encyclopedia of Philosophy calls him the last "universal genius", with contributions from philosophy to geology, law and history. Britannica adds that he discovered the fundamental theorem of calculus independently of Newton.

Maria Sibylla Merian (1647 to 1717). A German-born naturalist and artist. In 1699 she and her daughter Dorothea Maria set sail for Suriname on a projected five-year expedition, and in 1705 she published her book on the insects of Suriname. She was 52 when she left.

Sor Juana Inés de la Cruz (c. 1651 to 1695). A poet, dramatist, scholar and nun in colonial Mexico. Britannica says convent life gave her time to study, and that she built one of the largest private libraries in the New World, along with musical and scientific instruments. Her 1691 Respuesta defended all women's right to knowledge.

Which 18th and 19th Century Polymaths Stand Out?

Benjamin Franklin, Alexander von Humboldt, Mary Somerville, Ada Lovelace and Rabindranath Tagore. Science was turning professional, and these people worked across the boundaries anyway.

Benjamin Franklin (1706 to 1790). A printer, author, inventor, scientist and diplomat. In 1727 he organized the Junto, a club to debate morals, politics and natural philosophy. He later proposed an intercolonial version that led to the American Philosophical Society.

Alexander von Humboldt (1769 to 1859). From 1799 to 1804 he and Aimé Bonpland covered more than 6,000 miles of Central and South America. His climb of Chimborazo to 5,878 metres was a mountaineering record for nearly 30 years, and he was the first person to attribute mountain sickness to a lack of oxygen.

Mary Somerville (1780 to 1872). Her Mechanism of the Heavens (1831) was acclaimed by British mathematicians and astronomers, and her next book summarized astronomy, physics, geography and meteorology.

Ada Lovelace (1815 to 1852). In 1843 she added notes to a translation of an article on Charles Babbage's Analytical Engine, including a description of how it could be programmed to compute Bernoulli numbers. She has been called the first computer programmer, and she wrote that the engine "weaves algebraic patterns, just as the Jacquard-loom weaves flowers and leaves."

Rabindranath Tagore (1861 to 1941). A Bengali poet, song composer, playwright and painter. In 1913 he became the first non-European to win the Nobel Prize in Literature. In 1901 he founded an experimental school at Shantiniketan.

Who Are the 20th Century and Living Polymaths?

W.E.B. Du Bois, John von Neumann, Hedy Lamarr, Herbert A. Simon, Brian May and Mae Jemison. After 1900, nobody could reach the front edge of every field, so modern polymaths tend to combine a few.

W.E.B. Du Bois (1868 to 1963). Britannica calls him an American sociologist, historian, author, editor and civil rights activist. His essay collection The Souls of Black Folk (1903) is a landmark of African American literature.

John von Neumann (1903 to 1957). A Hungarian-born mathematician who pioneered game theory and, with Alan Turing and Claude Shannon, was one of the conceptual inventors of the stored-program digital computer.

Hedy Lamarr (c. 1914 to 2000). An Austrian-born film star who later gained recognition as the inventor of a radio communications device. Britannica notes it was never used in wartime but is a component of present-day satellite and cellular technology.

Herbert A. Simon (1916 to 2001). Britannica describes him as a social scientist known for work in psychology, mathematics, statistics and operations research. He shared the 1975 Turing Award with Allen Newell and won the 1978 Nobel Prize in Economics.

Brian May (born 1947). Queen's guitarist. He received a PhD from Imperial College London in 2007 for a thesis on zodiacal dust, and Imperial later reported he and a colleague had modelled the composition of zodiacal dust.

Mae Jemison (born 1956). A physician who served as a Peace Corps medical officer in West Africa before NASA selected her as an astronaut in 1987. In September 1992 she flew on the shuttle Endeavour as the first African American woman in space, and she holds a Stanford degree in chemical engineering and a Cornell medical degree.

Who Are the Famous Female Polymaths?

Seven of the 21 are women: Hypatia, Maria Sibylla Merian, Sor Juana Inés de la Cruz, Mary Somerville, Ada Lovelace, Hedy Lamarr and Mae Jemison. They worked in Alexandria, Germany and Suriname, colonial Mexico, Britain, Hollywood and NASA. This list is not a count of how many women were polymaths. It only reflects the people with well-documented careers in more than one field.

Who Was the Greatest Polymath in History?

There is no objective answer, because it depends on what you measure. Aristotle has a strong case for lasting influence. Leonardo is the usual pick for range of curiosity. Ibn Sina and Leibniz are strong picks for first-rate work in several fields at once.

Historian Peter Burke, writing in a Yale University Press essay, says that if there was a golden age of polymaths it ran from Leonardo in the fifteenth century to Humboldt in the early nineteenth, with Leibniz in between. He adds that people are now called polymaths for mastering "several" disciplines rather than "many." That is why the modern entries above combine two or three fields, not everything.

Are There Polymaths Alive Today?

Yes, but they usually combine a few fields. Mae Jemison and Brian May are two examples on this list, each with recognized work in fields far apart. Be cautious with online lists that name entrepreneurs with many side projects. Running companies in several industries is not the same as contributing to several fields of knowledge.

What Do Famous Polymaths Have in Common?

Reading these lives together, three patterns show up. This is our reading of the sources, not a research finding.

1. They kept records. Leonardo left more than 10,000 pages of notes, Shen Kuo's notebook ranged from compasses to fossils, and Lovelace's notes ran alongside the article she translated.

2. They went deep in turns, not all at once. Merian made her Suriname trip at 52, and Simon moved between psychology, economics and computer science across a long career.

3. They worked with other people. Franklin ran the Junto, Humboldt travelled with Bonpland, and Lovelace worked with Babbage.

There is also a modern link between a second interest and success in science. A 2008 survey by Root-Bernstein and colleagues found Nobel laureates averaged 0.94 arts or crafts hobbies per person, against 0.33 for Sigma Xi members. That is a correlation, not proof that hobbies cause prizes.

How Can You Learn Like a Polymath?

Pick a second field, learn it by recalling rather than rereading, and make something with it. The full step-by-step plan is in the definition guide linked at the top of this page. For the method behind it, see active recall and how to learn anything fast.

Morso can help with the first map of a field. Type a topic and Morso builds a course of bite-sized lessons, and each lesson ends with a quiz that makes you recall what you just learned. A few topics inspired by this list, if you want somewhere to start:

• How the human eye sees, from Ibn al-Haytham's optics

• Magnetic declination and how a compass works

• Bernoulli numbers and the first computer programs

• Game theory basics

• How frequency hopping works

• How mountain sickness happens at altitude

Here is the honest limit. A course gives you orientation and gets the basics into memory. It does not replace practice, feedback and years of work, and none of the people above learned that way. Try one free and see which topic pulls you in.

The Bottom Line

The famous polymaths were not people who knew a little about everything. They went deep in more than one field, usually in turns, and many of them wrote things down and worked with others. You do not need to match Leonardo. Pick one person from this list whose field you have never studied, and learn the basics of it this week.
