Fitzgerald, George Francis (1851–1901)

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.
