Dr Keith Norrish, a distinguished earth scientist and great pioneer of X-ray Fluorescence (XRF) spectrometry, passed away on September 13th, 2017, aged 93. Malvern PANalytical would like to acknowledge his life-time contribution to the XRF technique. Inspirational, sometimes fearless, Keith Norrish was a superb practician who made significant advances in the practical application of XRF. His work led to developments in instrumentation, sample preparation techniques (e.g. borate fusion) and multi-element instrument drift monitor samples.  Dr Norrish’s analytical methods are used widely in the mining sector, not only of his native Australia, but also worldwide and have led to the wider adoption of XRF in industry. For these outstanding contributions, he will be remembered.
