The compleat challenger--Dr. Harry S. N. Greene.

Speaking for Dr. Greene's former students, I would like to extend our sympathy and warmest wishes to the Greene family. The essence of Harry Greene's life was a consistent search for what was true, real, and meaningful in life and science, with little concern for images. This led him to hold personal value standards that differed in some ways from those held by others. In his scale of values, his family obviously meant a great deal. The genuine interest which he took in the families of many of us who worked under him and his willingness to share some of his own family life with his students spoke eloquently of the important place that family occupied in his life. So Jean, Judy, Susie, and Missie, we wish you well and hope that you will let us include you in our families in the years ahead as Harry and you did for so many of us. Now I would like to recreate a little bit of what it was like to be a student of Dr. Greene; and what this has meant to me subsequently. When our class first encountered Harry, 13 years ago, in the second-year pathology course, it was apparent to all that he was no ordinary professor or doctor. His message to us in the introductory lectures was a clear challenge to get involved in a meaningful search for knowledge. The challenge was delivered in his unique spirit and style so that it was impossible to be indifferent. This is what made him such an effective teacher. He had no problem with a generation gap. He forced the students to respond, and the range of responses was something to behold-from determination to accept the challenge, to open-mouthed disbelief. To illustrate how his message was delivered, I recall his response to a student's question as to which textbook he should read to learn pathology. Harry's colorfully worded caustic description of each of the standard textbooks elicited considerable merriment. But it was also clear that the proper way to use a textbook was to make observations from your own cases, and then read about it in the book. Whenever you discovered something in the book that wasn't true, tear out that page, and replace it with your own, based on careful personal observation. Before long, you would have a worthwhile loose-leaf textbook! For those tempted to accept Harry's challenge, the already established
