As noted in previous chapters, the discovery of the universe of galaxies was accomplished through slow but steady progress. However, since 1945 the pace of change in understanding galaxies has increased at a rapid rate. In the earlier days, as we have been discussing so far, certain individuals— for example, Messier, the Herschels, Rosse, Huggins, Barnard, Shapley, Hubble—made towering contributions, and therefore command the attention of the chronicler of the nebulae.
