Fitzgerald, George Francis (1851–1901)
George Fitzgerald was an Irish physicist who researched electrolysis and electromagnetism who is noted
for his theory of electromagnetic radiation.
As an explanation of the Michelson-Morley
experiment to determine the Earth's motion through the ether, Fitzgerald
suggested the theory that objects change length (Lorentz-Fitzgerald
contraction) along the direction in which they are moving. This was
important to Albert Einstein when he devised
his special theory.
