Thank you all. It is indeed H. L. Hunt.
Here is an interesting question that I am sure many have written about: I know a number of things that I cannot at the moment recall, but with enough effort I can retrieve many of them from my memory. For example, sometimes I cannot recall Donald Sutherland's name even though I can tell you the movies he was in and what he looks like. There are also countless things I do not know and perhaps have never known that I can retrieve from Google in much less time than it takes me to recall one of the things I do know, such as, say, the capital of South Dakota. Why should I not consider that vast store of information part of what I know?
