Short appreciation by Professor David Southwood:
Jim Dungey passed away last week. A light went out for me. I feel some echo of that must have been felt by everybody in the MIST community. He was an extraordinary scientist, someone out of the ordinary. His style was terse. In two pages in Physical Review Letters in 1961 he resolved the basis of solar-terrestrial interaction. He famously conceived it whilst stirring a coffee at a pavement café on Boulevard Montparnasse in Paris. Almost every sentence contains a nugget. Conversations with him could be as dense. I suspect that I am not the only one of his students for whom meetings during his PhD supervision were a matter of grasping clues and only later, often much later, appreciating the true import of what had been said. Indeed, in respect of his 1961 paper, it took the community as a whole almost 20 years to grasp the basic idea. The enormity of the 1961 paper's ultimate impact distracts from the number of other seeds he sowed: geomagnetic pulsations were standing MHD waves in the magnetosphere, Kelvin-Helmholtz instability could be important at the magnetopause, that the radiation belts had an external origin, that whistlers could determine the equilibrium of the belts, that magnetospheric MHD waves could be excited by bounce-drift resonance. I could continue and will, indeed, say more elsewhere. Moreover, he was a theorist but he welcomed any kind of experimental data, ground-based, space based and he also appreciated, long before I did, the interpretation of computer simulations. He was a MIST community member and a regular attendee at early meetings. His students and 'grand-students' are all around us. Everybody in the UK MIST community should feel the loss but, I hope, also a small pride that he was one of us.
