Harry’s increasing success with his Brighton hotels and his philanthropic activities eventually led him into the august company of Edward, Prince of Wales (later to become King Edward VIII), and his brothers George, Duke of York (later to become King George VI), and George, Duke of Kent.
From 1920 he staged a boxing tournament annually in the Brighton Dome in aid of the Royal Sussex County Hospital and the Royal Alexandra Hospital for Children. This event was a huge success, raising a great deal of money for these hospitals, largely because Harry managed to enlist the voluntary services of many top rank boxers and both the Prince of Wales and Duke of York as patrons.
Harry gave exhibition bouts himself and the Prince would attend, stopping in the Royal Albion. Later, Harry would have the honour of being invited to dine with the Prince at both Manor House Hove and St James’s Palace.
