The PQ industry has lost another giant with the passing in June of Erich Gunther, formerly of Electrotek Concepts and co-founder of Enernex. Erich had a unique capability to be truly a jack-of-all-trades and master-of-all, with regards to the utility electrical and communication systems, electronic instrumentation design, and programming of complex algorithms in software and firmware. His approach to seeing no problem as insurmountable if enough energy and enthusiasm were applied to it was felt and appreciated by many of us who were fortunate enough to be caught up in the "Gunther-wake". Erich was a driving force at all levels in the IEEE PES work, from writing a chapter for a new standard, to leading the formation of the Smart Grid Initiatives group into a Standards Committee, to serving on the Executive Board.  Numerous utilities have benefitted directly from his expertise and his mark on the PQ industry is vast. His legacy will be endless, and his presence and contributions going forward greatly missed. No more will we be able to say "Erich, please explain this…..”.
