Shapley did not differentiate himself only in research. Soon the world and not only the astronomers, learned to know him as an outstanding lecturer and successful writer. In 1920 Shapley was offered directorship of the Harvard College Observatory, when the latter fell vacant on the death of E. C. Pickering (1846-1919). Shapley accepted; and this observatory was to remain his academic home for the rest of his life.
