Hans Charles Freeman 1929–2008 (2022)


Hans Freeman was born in Germany and arrived in Australia with his parents in 1938. A brilliant student at the University of Sydney, he spent a seminal year at the California Institute of Technology before joining the staff at Sydney and initiating research on bioinorganic chemistry, studying metal ion complexes of compounds of biological significance such as amino acids, peptides and proteins. In his use of X-ray crystallography he was a pioneer in Australia, constructing his first crystallographic apparatus and mastering the necessary computing, at first by hand but soon with electronic computers. The culmination of his work with a series of collaborators was the structure of the blue, copper-containing metalloprotein, plastocyanin. Freeman also employed another advanced technique—X-ray spectroscopy and the study of X-ray absorption fine structure. He was a leading figure in Australia and internationally, and played an important role in gaining access for Australian scientists to international facilities such as synchrotron radiation sources at the dawning of the era of ‘Big Science’.
