Ladies and Gentlemen: In my practice of geriatrics, it has been customary for me to advise my aging and old patients not to dwell too much on the past, but rather to cultivate the present and make plans for the future. On the other hand, I am by no means blind to the fact that memory can indeed be a precious and blessed gift of nature. Therefore, I shall disobey my own prescription today and indulge in a few reminiscences, particularly those that have to do with personal contacts I have had with some famous sexologists of the past.
