Richard Alan Morton was the child of Welsh-speaking parents in Liverpool. His middle name was initially Alun. He attended the co-educational Oulton Secondary School in Liverpool. He left school in 1917 to work in a pharmacy and then joined the army towards the end of the First World War. He became ill with Spanish flu. From 1919 he studied chemistry at the University of Liverpool, graduating with B. Sc. first class in 1922. He then undertook doctoral research supervised by Edward Charles Cyril Baly into the application of optical spectroscopy. Selig Hecht was a post-doctoral fellow with Balys group at this time, interested in applications of spectroscopy in biology, and this developed Mortons interest in this new application.
