Passage: The one-day ceremony took 14 months of preparation: the first meeting of the Coronation Commission was in April 1952, under the chairmanship of the Queen's husband, Philip, Duke of Edinburgh. Other committees were also formed, such as the Coronation Joint Committee and the Coronation Executive Committee, both chaired by the Duke of Norfolk who, by convention as Earl Marshal, had overall responsibility for the event. Many physical preparations and decorations along the route were the responsibility of David Eccles, Minister of Works. Eccles described his role and that of the Earl Marshal: "The Earl Marshal is the producer – I am the stage manager..."
