Bragg, William Lawrence, work

His work, called a classical example of the scientific method, was the second and last of his independent publications. Despite the pleadings of his colleagues, he enlisted in the British Army at the outbreak of World War I, and was killed in battle on August 10, 1915. see also Bohr, Niels Bragg, William Lawrence Lanthanides Radiation Rutherford, Ernest. 

Equation (16.3) is called the Bragg equation, after William Henry Bragg (1862-1942) and his son William Lawrence Bragg (1890-1972). They shared the Nobel Prize in physics in 1915 for their pioneering work in X-ray crystallography. 

Langmuir never states where he got the clue for this leap. But comments he makes in a later paper, coupled with some strong circumstantial evidence, allows one to infer a likely source of the idea. That source is the work on crystal structure of William Henry and William Lawrence Bragg,... 

Following the discovery in 1912 by William Heruy Bragg and his son William Lawrence Bragg that x-rays were diffracted by crystals, Debye reported that the thermal vibrations of the atoms in crystals affected the x-ray patterns. Based on his work on heat capacities (specific heats), he determined the temperature dependence of the intensity of the diffraction pattern. This led him to consider the x-ray diffraction of randomly oriented molecules. 

The X-ray diffraction method is most easily applied to crystalline solids. The pioneering work in this field was done in 1912 and 1913, by the British physicist Sir William H. Bragg (1862-1942) and his son Sir Lawrence Bragg. Figure 3.5 shows a schematic diagram of the Bragg X-ray spectrometer. The same principle is used in most modern instruments, which are widely used to study crystals and other solid materials. The technique can be applied either to single crystals or to powders.
