William Lawrence Bragg was an Australian-British physicist, who won the Nobel Prize for Physics at the age of 25 and is the youngest ever Nobel Laureate in Physics so far. He and his father, William Henry Bragg, shared the ‘Nobel Prize for Physics’ awarded in 1915 for their work involving x-ray crystallography. Although he was a talented and able individual from an early age, it was assumed that his father had produced the bulk of the work and then generously shared the prize with his son for assisting him. But it was he who had the key idea and the skill to interpret the diffraction patterns to prove it and his father had contributed primarily developing instruments for the experiment. The effect of this slighting on him would shadow him for the rest of his life. He served for British army in both the World Wars and later became a popular lecturer known for his skill in making science exciting for the students. He enjoyed his job as a professor and most reports indicate he found happiness at the Royal Institute for perhaps the first time in his life. The foundation laid by his work and that of others in x-ray crystallography helped scientists to discover the structures of DNA and RNA, thereby creating the field of molecular biology.
