Hubble's Nobel Prize

Astronomy is not in the list of natural sciences aimed at by the Nobel awards. In spite of that, there were, throughout the 1930s until the early 1950s, effective moves by important scientists to distinguish Hubble with the Prize. A short report on these attempts is made as well as speculation on what would be the citation for the prize in view of the broad range of Hubble's scientific achievements. Within this context, the opportunity is also taken for publicizing the Crafoord Prize which does consider astronomy.
