My favourite memories of Karl are of his repeated success, until he disqualified himself to give someone else a chance, in winning the "shootout" spectral data analysis competition at Chambersburg. It was like watching amateurs play against a grand master. When I'm tempted to feel proud of some sophisticated chemometric analysis, I try to remember that Karl would almost certainly have been able to beat my efforts with a deceptively simple regression equation and with a smile on his face.

His passing is the end of an era, and he will be sorely missed by the whole community of NIR researchers that has grown from the seed he sowed.
