In his 2019 Fankuchen Award Lecture, Eaton E. Lattman provided an excellent introduction to SAXS (small-angle X-ray scattering) in solution.

TobyDreeleBrian H. Toby and Robert Von Dreele shared the 2019 Trueblood Award for their collaborative work in developing GSAS-II. The movie of their presentation is now online. 

Bryan CBryan C. Chakoumakos described his research with single-crystal neutron diffraction at Oak Ridge National Laboratory in this video of his 2019 Bau Award lecture.

Soriano-Garcia Manuel Soriano-García was educated in Mexico and  received his Ph.D. in biophysics under the direction of Rengachary Parthasarathy at SUNY Buffalo. As Research Professor at the National Autonomous University of México he established small-molecule and protein crystallography in Mexico, receiving many national awards.

rognlieThe biography of David G. Rognlie describes his approach to the business of supplying diffraction equipment to ACA members. The ACA Award in Dave's honor mentions his "generosity of spirit, optimism, selflessness, and desire to help others." 

MegawHelen Megaw (1907-2002) was a British crystallographer who specialized in perovskite structures, ferroelectricity, and feldspars at the Cavendish laboratory. She, Bragg, Hodgkin, and Lonsdale created designs for the Festival of Britian in 1951.


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 videos to our YouTube channel.
