Educated at Charterhouse School in Surrey and Trinity College, Cambridge, Morrison was a talented all-round sportsman. While at Cambirdge he won three Blues (first-team colours) for cricket, football and golf. As an amateur he represented England at football and played first-class cricket at county level with Somerset (as his future golf design partner Hugh Alison had done).

During the 1914-18 War, Morrison joined the Royal Flying Corps and won the DFC and Bar and Italian silver and bronze medals for valour flying "stringbag" torpedo bombers in Italy. He then joined the newly formed Royal Naval Air Service, and is reported to have been one of the first pilots to land a plane on an aircraft carrier. In the Second World War, he was initially a Wing Commander then a Group Captain in charge of a training wing.

Starting out in golf architecture as an assistant to Harry Colt in 1924, Morrison worked on a number of courses and remodelling projects. In 1928 his relationship with Colt and Colt's long-time partner Charles Hugh Alison was formalised with the establishment of the golf architecture firm of Colt, Alison & Morrison Ltd. Morrison carried the firm's banner, particularly into Continental Europe.

When Colt died in 1951 and then Alison a year after that, it was left to Morrison to continue the firm, which he did until his own death in 1961.
