Jon Driver was a stunningly scientist, and probably the most brilliant experimentalist I have ever known. He had an incredibly sharp intuition for the key theoretical issues and the decisive experiments to address them; and the ability to construct experimental designs of rigour and, often, real beauty. His experimental work was relentlessly innovative on just about every dimension. One had the sense that, rather than making marginal adjustments to existing paradigms, Jon was able to create just what was needed from first principles, albeit informed by a vast knowledge of prior work. His work will stand as a paradigm example of what can be achieved, for anyone interested in the experimental study of the mind and brain.
I did not know Jon well; but I always found talking with him about research incredibly stimulating and inspiring. He was modest about his remarkable achievements and generous in his assessment of others. He seemed entirely free of dogma; just genuinely open to finding out the truth by the most powerful available tools. Jon's approach to research was inspiring, playful, and devastatingly effective; a pleasure to watch, even from a distance. I regret very much that I did not have more chance to get to know him as a man, and to see his remarkable powers as a scientist.
His work and influence will continue to shape our field for many decades; and I believe that he will be remembered, by present and future generations, as one of the most remarkable investigators into the mind and brain that Britain has ever produced.
