Max Wolf: The Twenty-fifth Bruce Medalist

Minor planets (asteroids) have been much in the news lately, while clusters of galaxies and the structure of the interstellar medium are among the hottest topics of astronomical research. All three of these fields owe much to Max Wolf. Five years younger than Edward E. Barnard and five years older than George E. Hale, Wolf combined Hale's self-confidence and initiative with Barnard's persistence.
