In line with researchers like Koestler, Martindale or Guilford he pointed out that a creative, innovative person values or should value interdisciplinary work. <The more the world makes up specialists, the more we should strive to become generalists> was his advice.12 According to him, the most important features of creative persons are the non-acceptance of stock answers and the production of associative ideas, transferring a new concept from one field to another, breaking the pattern of the familiar. What activities are particularly useful for fostering creativity? Obviously, for a person like Kock music-making and especially composing are relevant. But there are others, for example chess. Kock pointed out that several eminent scientists like Turing, Wiener or Shannon championed chess as an ideal proving ground for research.13 Chess problem composing is particularly important. Kock was a superb chess player himself. But also, and coming back to my quotation from Kock’s book at the beginning: Literature, writing short stories, novels and poems should be valued highly. Closely linked to chess problem composing is the writing of mystery novels. But other fields of literature are useful too: Kock mentions that many science and engineering innovators moved into the field of science fiction writing, e.g. Arthur C. Clarke, who pioneered in suggesting a communication satellite, or Bell Lab’s inventor John R. Pierce, who, inter alia, was, together with Rudolph Kompfner, responsible for the microwave amplifier, the <travelling-wave> tube. Authors of cartoons and humorous columns should also not be forgotten. They have to come up with novel ideas and the unexpected all the time if they are to maintain a following.14
