Zeeman PETER (Zeeman, Pieter) (1865-1943), a Dutch physicist. Born May 25, 1865 in Zonnemayre (Zeeland Province). He graduated from the University of Leiden (1890), worked as a teacher. Since 1897 - Associate Professor of the University of Amsterdam. In 1900 he became a professor, and in 1908 - the director of the Physics Institute in Amsterdam.
In 1896 Zeeman studied the emission spectrum of sodium vapor in a powerful electromagnet field. Like Faraday, who put a similar experience in 1862, he watched the yellow D-line with a spectroscope, but used the device with higher resolution. He discovered that the spectral lines are split (the Zeeman effect) in a strong magnetic field. By repeating the experiment with a spectroscope even higher resolution, Zeeman in 1897 according to their measurements accurately determined the ratio of the electron charge to its mass. The theory of the Zeeman effect proposed in 1897 H.Lorents. Zeeman effect was undeniable proof of the electromagnetic nature dawns 1902 Zeeman and Lorentz received the Nobel Prize in physics for the study of the influence of magnetic field on the processes of radiation. Among other honors Zeeman - medals and G.Drepera B.Rumforda. Zeeman was elected a Fellow of the Royal Society and the French Academy of Sciences. Died Zeeman in Amsterdam October 9, 1943.
