Observations on Laue diffraction within synchrotron radiation and neutron macromolecular crystallography research and developments.

A seminal contribution in the domain of physiologically relevant biological structure and function determination was by Keith Moffat, of Cornell and latterly of the University of Chicago proposing that synchrotrons should offer the option of a Laue method data collection mode. I enthusiastically joined in supporting this initiative. This proposal needed detailed methods development though; theoretical, experimental and software development. This work was added to the broad research and development program of synchrotron radiation at the UK's SRS. This whole program led to knowledge transfer from the UK's SRS to the ESRF as well as for neutron Laue protein crystallography to the reactor spallation sources and later to spallation neutron sources.
