Hans Freeman

Hans Charles Freeman AM, FAA (26 May 1929 – 9 November 2008) was a German-born Australian bioinorganic chemist, protein crystallographer, and professor of inorganic chemistry who spent most of his academic career at the University of Sydney. His best known contributions to chemistry were his work explaining the unusual structural, electrochemical, and spectroscopic properties of blue copper proteins, particularly plastocyanin. He also introduced protein crystallography to Australia and was a strong advocate for courses to ensure Australian scientists have good access to "big science" facilities. Freeman has received numerous honours, including being elected a Fellow of the Australian Academy of Science (FAA) and appointed a Member of the Order of Australia (AM) by the Australian Government. He was a charismatic lecturer who voluntarily continued teaching well into his formal retirement and imbued his students with a love of science.
