## Lorentz, Hendrik Antoon (1853–1928)electron theory, that light occurred through
motion of electrons in a stationary electromagnetic
ether. Thus the wavelength
should change under the influence of a powerful magnetic
field; and this was experimentally shown by Zeeman (1896). See also
Zeeman effect. But the theory was inconsistent with the results of the Michelson-Morley experiment, and so Lorentz introduced the idea of "local time," that the rate of passage of time differed from place to place; and, incorporating this with the proposal of George Fitzgerald that the length of a moving body decreases in the direction of motion (the Lorentz-Fitzgerald contraction, or Lorentz contraction), he derived the Lorentz transformation,
a mathematical statement which describes the changes in length, time, and
mass of a moving body. His work, with that of Fitzgerald, laid the foundations
for Einstein's Special
Theory of Relativity. ## Related category• PHYSICISTS | ||||||
