A polymath (πολυμαθής; homo universalis) is an individual whose knowledge spans a substantial number of subjects, known to draw on complex bodies of knowledge to solve specific problems.
In Western Europe, the first work to use the term polymathy in its title (De Polymathia tractatio: integri operis de studiis veterum) was published in 1603 by Johann von Wowern, a Hamburg philosopher. Von Wowern defined polymathy as "knowledge of various matters, drawn from all kinds of studies ... ranging freely through all the fields of the disciplines, as far as the human mind, with unwearied industry, is able to pursue them". Von Wowern lists erudition, literature, philology, philomathy, and polyhistory as synonyms.
The earliest recorded use of the term in the English language is from 1624, in the second edition of The Anatomy of Melancholy by Robert Burton; the form polymathist is slightly older, first appearing in the Diatribae upon the first part of the late History of Tithes of Richard Montagu in 1621. Use in English of the similar term polyhistor dates from the late 16th century.
Polymaths include the great scholars and thinkers of the Renaissance and Enlightenment, who excelled at several fields in science, technology, engineering, mathematics, and the arts. In the Italian Renaissance, the idea of the polymath was allegedly expressed by Leon Battista Alberti (1404–1472), a polymath himself, in the statement that "a man can do all things if he will". Gottfried Wilhelm Leibniz has often been seen as a polymath. Al-Biruni was also a polymath. other well-known and celebrated polymaths include Leonardo da Vinci, Ibn al-Haytham, Rabindranath Tagore, Mikhail Lomonosov, Alan Turing, Benjamin Franklin, John von Neumann, Charles Sanders Peirce, Henri Poincaré, Isaac Asimov, Nicolaus Copernicus, René Descartes, Aristotle, Averroes, Blaise Pascal, Wang Wei, Isaac Newton, Nikola Tesla, Thomas Edison, Bertrand Russell, Thomas Young and Thomas Jefferson.
