Recollections of Early Laboratory Experiments on Vision

My task is to describe, for readers mostly younger than myself, a half century of experience in the field of vision research. But there are two formidable barriers to this communication. First, I can scarcely remember the impetuous and inexperienced person that I was so long ago; and secondly, the world itself has changed so radically since then. As Andre Maurois once said, “The minds of different generations are as impenetrable one by the other as are the monads of Leibniz.” I never could understand Leibniz.
