(Sir) Alan Walsh was the originator and developer of the atomic absorption method of chemical analysis, which has been described as 'the most significant advance in chemical analysis' in the twentieth century. Walsh claimed this breakthrough came about when he “managed to stop being stupid long enough to see something that should have been obvious all along”. The first spectrometer based on his design was produced in Australia during the mid-1960s by Techtron Pty. Ltd. Atomic absorption provided a quick, easy, accurate and highly sensitive method of determining the concentrations of more than sixty-five of the elements, rendering traditional wet-chemical methods obsolete. The method has found important application world-wide in areas as diverse as medicine, agriculture, mineral exploration, metallurgy, food analysis, biochemistry, the wine industry and environmental control. Alan Walsh was leader of the Spectroscopy Section of the CSIRO Division of Chemical Physics from 1946-57 and Assistant Chief of the Division from 1958-76.
