In 1901 Wilhelm Konrad Roentgen was the first recipient of the Nobel Prize for Physics, and he truly deserves his place in history because his discovery revolutionized the medical world. A series of experiments helped him notice that barium platinocyanide emits a fluorescent glow. Combining his observation with a photographic plate and his wife's hand, he made the first X-ray photo, and thus, made it possible to look inside the human body without surgical intervention.
