About Pieter Zeeman

Pieter Zeeman was a Dutch experimental physicist who shared the 1902 Nobel Prize in Physics with Hendrik Lorentz for their discovery and theoretical explanation of the Zeeman effect. Hendrik Lorentz first heard about Zeeman's observations on Saturday 31 October 1896 at the meeting of the Royal Netherlands Academy of Arts and Sciences, where these results were communicated by Heike Kamerlingh Onnes. He discovered that a spectral line is split into several components in the presence of a magnetic field. Zeeman became interested in physics at an early age.
