LonsdaleHow do we know the benzene ring is flat? Because in 1929 Kathleen Lonsdale determined that the arrangement of the carbon atoms in hexamethylbenzene is hexagonal.  

DesirajuGautam 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.

stenkampIn Ronald Stenkamp's Living History he comments, "Making observations and asking questions is what I enjoy doing." He recalls small-molecule crystallography research at University of Oregon with Brian Matthews and graduate work in macromolecular crystallography with Lyle Jensen, Ed Lingafelter, and Verner Schomaker at the University of Washington. 


Michael RossmannThe 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

glazerA. Michael Glazer obtained his Ph.D. with Kathleen Lonsdale followed by a post-doc in Helen Megaw's   laboratory. He is well known for his research into       structure-property relationships in perovskites. 

Benno SThe video of Benno Schoenborn's 2016 ACA Bau Neutron Diffraction Award lecture is now online. Benno has been aptly called the "father of neutron protein crystallography," since he was the first to determine a protein structure (myoglobin) by neutron diffraction. 


 

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.
