George Francis Fitzgerald

George Fitzgerald was an Irish physicist who researched electrolysis and electromagnetism and 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.
