The Symposium opened with a morning devoted to the accomplishments and character of Henry Norris Russell, as one of the two originators of the Hertzsprung-Russell diagram, on the hundredth anniversary of his birth. The papers presented at this session, together with some shorter remarks made at other times during the Symposium, are to appear in a separate volume as Dudley Observatory Report. No. 13. Suffice it to say here that the picture which emerged was that of a fine man of enormous energy, prodigious memory, committed to his scientific work but with many interests, always polite and pleasant to those around him but somewhat remote.
