Edwin Hubble, the famous American astronomer, was interviewed at his home in California in 1952, just a year before his death. He spoke about his seminal determination in 1929 of a redshift–distance relation for the galaxies and how sought in vain to find the best cosmological model from an observational standpoint. His work was being continued at the new and powerful Mount Palomar Observatory, which Hubble described. Although Hubble is now known as the father of the expanding universe, he was uncertain of whether it is in fact expanding. Observational data are all-important and he said they do not clearly speak out in favour of an expanding universe. Hubble also indicated that he dislikes the intrusion of radioastronomy and nuclear astrophysics in modern astronomical science.
