  • Jean-Baptiste Biot1774–1862

    French physicist who co-discovered the Biot–Savart law, founded polarimetry through the laws of optical rotation, and established the extraterrestrial origin of meteorites.

    electromagnetism, optics, polarimetry

  • Hans Christian Ørsted1777–1851

    Danish physicist and chemist who discovered in 1820 that an electric current deflects a magnetic needle, founding electromagnetism.

    electromagnetism, physics, chemistry

  • François Arago1786–1853

    Astronomer and physicist who discovered chromatic polarization and magnetism of rotation, championed Fresnel's wave theory, led the Académie des sciences and abolished slavery in the French colonies as minister in 1848.

    astronomy, optics, electromagnetism

  • Michael Faraday1791–1867

    English experimental physicist and chemist who discovered electromagnetic induction, the laws of electrolysis, diamagnetism and the magneto-optical effect, and introduced the concept of the field.

    electromagnetism, electrochemistry, magneto-optics

  • Joseph Henry1797–1878

    American physicist who built the first powerful electromagnets, discovered self-induction and the oscillatory discharge, and was the first Secretary of the Smithsonian Institution.

    electromagnetism, electrical engineering, acoustics

  • Wilhelm Weber1804–1891

    German physicist who with Gauss founded absolute electromagnetic measurement and an early telegraph, proposed the first unified force law for moving charges, and with Kohlrausch measured the ratio of units that pointed to the speed of light.

    electromagnetism, geomagnetism, metrology

  • James Clerk Maxwell1831–1879

    Scottish physicist who unified electricity, magnetism and light in a field theory and introduced statistical methods into physics.

    electromagnetism, kinetic theory, statistical mechanics

  • Oliver Heaviside1850–1925

    Self-taught English physicist who gave Maxwell's equations their modern vector form, founded transmission-line theory and invented operational calculus.

    electromagnetism, electrical engineering, transmission-line theory

  • Hendrik Antoon Lorentz1853–1928

    Founder of the electron theory of matter, author of the Lorentz force and the Lorentz transformation, and 1902 Nobel laureate for the theory of the Zeeman effect.

    theoretical physics, electromagnetism, electron theory

  • J. J. Thomson1856–1940

    Physicist who identified the electron as a universal constituent of matter, proposed the first electron model of the atom, separated isotopes of neon with positive rays, and directed the Cavendish Laboratory for 35 years.

    atomic physics, electromagnetism, conduction in gases

  • Heinrich Hertz1857–1894

    Experimental physicist who produced and detected electromagnetic waves, confirming Maxwell's theory, and founded the theory of elastic contact.

    electromagnetism, contact mechanics, mechanics

  • Guglielmo Marconi1874–1937

    Italian inventor and entrepreneur who developed practical long-distance wireless telegraphy, shared the 1909 Nobel Prize in Physics, and became a leading scientific official of Fascist Italy.
