the autumn of 1912, when he was only 22 years old, William
Lawrence Bragg realised that X-rays could be used to
detect the arrangement of individual atoms inside solid
crystals. With his father's help he created a new science
of X-ray crystallography.
his insight, Lawrence Bragg became the youngest ever
Nobel Laureate in 1915. He went on to become the Cavendish
Professor of Experimental Physics. In 1953, more
than forty years after his discovery he saw X-ray crystallography
used to reveal the structure of DNA.
