The title for this paper was suggested by Ed Dahl. It is autobiographical, as he requested, and could also be titled, informally, “A Trip down Memory Lane.” My assignment from Ed is autobiographical, personal, and selective—even, impressionistic. This account covers more than eighty years. I hope no one will be offended if their name is not mentioned; and I also hope it doesn’t turn out to be what my grandchildren call an “ego trip.” This is one person’s view of a good deal of institutional history, and is not, I know, the last word on the subject. About one third of the period covered is from before I was involved with the Society for the History of Discoveries (SHD).
