Welcome to the History Portal of the ACA


The ACA History Project showcases and preserves the history of crystallography, X-ray diffraction, and structural science through online access, articles in ACA RefleXions quarterly magazine, and archival at the Niels Bohr Library and Archives in College Park, MD. 


In celebration of the international nature of structural science, here are links to other history resources. For example, Elspeth Garman gave the 2016 Rosalind Franklin lecture, "From chocolate to drug discovery - what crystallography has done for the world."
