Born 18 Jul 1853; died 4 Feb 1928 at age 74.
Dutch physicist who shared (with Pieter Zeeman) the Nobel Prize for Physics in 1902 for his theory of the influence of magnetism upon electromagnetic radiation phenomena. The theory was confirmed by findings of Zeeman and gave rise to Albert Einstein's special theory of relativity. From the start, Lorentz made it his task to extend James Clerk Maxwell's theory of electricity and of light. Already in his doctor's thesis, he treated the reflection and refraction phenomena of light from this new standpoint. His fundamental work in the fields of optics and electricity revolutionized conceptions of the nature of matter. In 1878, he published an essay relating the velocity of light in a medium, to its density and composition.
