Museum of Crystallographic Instruments?

The prototype 4 Circle Diffractometer designed and used by David Harker.

The Smithsonian's National Museum of American History, in conjunction with the ACA, is working to locate historically significant X-ray crystallographic instruments used in determining molecular structures of organic and biologically active macromolecules. The goal is to preserve these important instruments in the US National Collections and other sites for the education and enjoyment of future generations. Initially, we will be interested only in instruments made before 1970. A second phase will bring the collection close to the present. We know that all of you have busy schedules of research, teaching, and administration, but if you agree with us that X-ray crystallography has played a crucial role in Science, please help us in this effort for the benefit of later generations.

Please send any information about the location of significant instruments, thoughts about why they are important, or any ideas about the project to: J. Eklund, Curator of the History of Chemistry, NMAH 5122, MRC 637, Smithsonian Inst., Washington, DC 20560, USA. FAX: 202-357-1853. Please do not send any instruments at this time.
