William Thomas Astbury FRS (25 February 1898 – 4 June 1961) was an English physicist and molecular biologist who made pioneering X-ray diffraction studies of biological molecules. [1] His work on keratin provided the foundation for Linus Pauling 's discovery of the alpha helix. He also studied the structure for DNA in 1937 and made the first ...
Jun 3, 2019 · William Thomas Astbury (1898–1961) William Thomas Astbury studied the structures of fibrous materials, including fabrics, proteins, and deoxyribonucleic acid, or DNA, in England during the twentieth century. Astbury employed X-ray crystallography, a technique in which scientists use X-rays to learn about the molecular structures of materials.
Apr 23, 2013 · 1943: X-ray Diffraction of DNA. William Astbury, a British scientist, obtained the first X-ray diffraction pattern of DNA. X-ray diffraction patterns of crystallized molecules can reveal their structures with atomic precision. Astbury obtained X-ray diffraction patterns of uncrystallized DNA. He extracted DNA from cells, then dipped a needle ...

structure William T. Astbury. They have suggested that Astbury’s failure to capitalize on the photograph to solve DNA’s structure was due either to his being too much of a physicist, with too little interest in or knowledge of biology, or to his being misled by an erroneous theoretical model of the gene. Drawing on
