Henry Bragg was a notable figure in the field of physics, particularly known for his contributions to the study of X-ray crystallography. He was born in 1864 and later became a professor at University College London. His work significantly advanced the understanding of crystal structures and their properties. In 1915, Henry Bragg, along with his son William Lawrence Bragg, was awarded the Nobel Prize in Physics for their joint research on the analysis of crystal structures using X-ray diffraction. This groundbreaking work laid the foundation for many scientific advancements in materials science and chemistry.
