Pieter Zeeman (1865 with Zonnemaire - 1943 with Amsterdam, Netherlands) was a Physicien Dutch which accepted in 1902 the Nobel Prize of physics.

It made its studies with the Université of Leyde, where it taught until he becomes professor of physics to the Université of Amsterdam in 1900.

This work concerned inter alia on the emission of Lumière by the excited Atome S and the Propagation of the light signals in the mediums moving. One owes him the discovery of the Effet Zeeman.

In 1886, Zeeman discovered that the spectral lines of a source of light subjected to a Magnetic field have several components, each one of them presenting a certain polarization. This phenomenon, called Zeeman effect thereafter, confirmed the electromagnetic theory of the light.

Zeeman divided, in 1902, the Nobel Prize of physics with the Dutch physicist Hendrik Lorentz, for their common work on the influence of a magnetic field on the light radiation.

He is prize winner of the Médaille Rumford in 1922 and of the Franklin Médaille in 1925.
