Gautam Desiraju, past president of IUCr,  contributed formative concepts in crystal engineering and investigated weak hydrogen bonds. In his memoir he illustrates how a work may be conceived and how it may be received—and how these two features may be largely unconnected.


John C H Spence

In his Buerger Award lecture John Spence discussed XFEL, lensless imaging and serial femto-second nanocrystallography.

Michael Rossmann

The Michael G. Rossmann Memorial Session was held at the ACA Annual Meeting in Covington, KY. Five speakers described their experience in Michael’s laboratory, beginning in 1972 with Jack Johnson, then Eddy Arnold, Hao Wu, Rui Zhao, and S. Saif Hassan – 47 years of ground-breaking research in macromolecular structure and development of new crystallographic methods for large structures.

Alex WlodawerIn his memoir Alexander Wlodawer describes a lengthy career determining the structure of a variety of biologically important molecules, including HIV protease.
B. E. Warren

Read Bertram Warren's biography reprinted from Fifty Years of X-Ray Diffraction, ed. P.P. Ewald, International Union of Crystallography, 1962.

Benno SchoenbornBenno Schoenborn received the ACA Bau Neutron Diffraction Award in 2016 for his pioneering work on neutron crystallography and its application to biology. 


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.
