The team of William Henry and William Lawrence Bragg is certainly one of the most scientifically productive in history. Combining their intellect and research skills, they succeeded in constructing the first X-ray spectroscope, establishing the science of X-ray crystallography . They were jointly awarded the 1915 Nobel Prize for Physics and remain the only father-and-son team ever so honored. William Henry Bragg was educated on the Isle of Man, at King William's College. Always at the top of his classes, he was particularly talented in mathematics. He entered Cambridge at age nineteen to study physics under John William Strutt, Lord Rayleigh (1842-1919) and Sir Joseph J. Thomson (1856-1940). Thomson steered Bragg to an opening in the physics and mathematics department at the University of Adelaide, Australia, and Bragg undertook the long sea voyage, becoming a professor in 1886. During the next eighteen years, he would establish a reputation as a masterful...
