BIOGRAPHY OF H. A. LORENTZ

Hendrik Antoon Lorentz was Born at Arnhem, the Netherland, on July 18, 1853. He entered the University of Leyden in 1870, obatined his B. Sc. Degree in mathematics and physics in 1871. He returned to Arnhem in 1872 to become a night school teacher. At the same time, he prepared for his doctoral thesis on reflection and refraction of light. In 1875, at his early age of 22, he obtained his doctor’s degree.

In January 1928, H. A. Lorentz became seriously ill, and died shortly after on 4 february

From the start of his scientific work, Lorentz took 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 standpoint which was then quite new. His fundamental work in the fields of optics and electricity has revolutionized contemporary conceptions of the nature of matter.

In 1878, he published an essay on the relation between the velocity of light in a medium and the density and composition thereof. The resulting formula, proposed almost simultaneously by the Danish physicist Lorenz, has become known as the Lorenz-Lorentz formula.

When a colleague and former student of Lorentz’s, Pieter  Zeeman, discovered the Zeeman  effect in 1896, Lorentz supplied it Theoretical interpretation. The experimental and Theoretical work was honored with the Nobel Prize in Physics in 1902.
