Bruce Godfrey Hyde 1925-2014

Bruce Hyde made seminal contributions to modern solid state chemistry, in particular to the understanding and characterization of non-stoichiometry and structural complexity in the solid state. His work showed unequivocally that non-stoichiometric crystalline materialswere often much more highly ordered than previously believed, that the point defects of conventional wisdom were in fact ordered into extended defects and that these defects were themselves ordered into structures of complexities hitherto unimagined. His deep understanding of crystal chemistry and structural relationships is apparent in his two co-authored books with his closest colleagues, Sten Andersson and Michael OKeeffe. It also led to his mentoring an entire generation of younger Australian (and international) solid state chemists.
