Early life Born in Ireland in Lurgan, County Armagh, on 25 December 1881, John Greer Dill's father, also named John, (and who died when the younger John was just twelve years old) was the local bank manager and his mother, Jane, (who died just months after her husband) was a Greer from Woodville, Lurgan. With the death of both parents, "John and his sister were then cared for by an uncle, the Reverend Joseph Grundy Burton".
Always intended for a career in the armed forces, Dill, along with his sister, Nicolina Frances, attended Methodist College Belfast, from 1887 to 1889. This was followed by his education at Cheltenham College in Gloucestershire, England and the Royal Military College, Sandhurst. According to historian Richard Doherty, Dill's conduct at Sandhurst were "exemplary" although there "were no indications of the outstanding intelligence for which he would later be noted and his marks were described as mediocre".
Early life and military career From Sandhurst Dill was commissioned on 8 May 1901 as a second lieutenant into the 1st Battalion of the Leinster Regiment,
Dill, by now a lieutenant since 15 August 1903 (later antedated to 27 May), was appointed as his battalion's adjutant on 15 August 1906, having previously been assistant adjutant from 1902. and was still there on the outbreak of the First World War eighteen months later.

During 1916 Dill, promoted in May to major, served on the General Staff of the 55th (West Lancashire) Division and Canadian Corps, before being promoted to Lieutenant-Colonel and Chief of Staff (GSO1) of the 37th Division in January 1917. and had been mentioned in despatches eight times.

He was appointed a Companion of the Order of St Michael and St George (CMG) in the 1918 New Year Honours. He also received a number of foreign decorations for his service, including the Officer of the Legion of Honour, the French Croix de guerre, Commander of the Order of the Crown of Belgium, Officer of the Order of the Crown of Romania. returned to the Staff College and served as an instructor there.

Faced with the prospect of a German invasion, Dill produced a memorandum on 15 June advocating the use of chemical warfare against an enemy landing. Although acknowledging that first use of chemical weapons would alienate the United States and invite retaliation, he concluded that "at a time when our National existence is at stake ... we should not hesitate to adopt whatever means appear to offer the best chance of success."
After criticism from the Director of Home Defence and other offices Dill withdrew the memorandum. Nevertheless, the proposal was largely endorsed by Churchill on 30 June and it was ordered that the Royal Air Force begin preparations for deploying mustard gas, although he added that actual employment would need to be ordered by the Cabinet. and posted him to Washington, D.C. as his personal representative where he became Chief of the British Joint Staff Mission, then Senior British Representative on the Combined Chiefs of Staff. Dill showed a great flair as a diplomatic military presence. In 1943 alone he attended the Quebec Conference, the Casablanca Conference, the Tehran Conference and meetings in India, China and Brazil. He also served on the Combined Policy Committee set up by the British and United States governments under the Quebec Agreement to oversee the construction of the atomic bomb. He was awarded the Howland Memorial Prize in 1944, in part to ensure his continued favour with Churchill.
In the United States he was immensely important in making the Chiefs of Staff committee – which included members from both countries – function, often promoting unity of action. He was particularly friendly with General George Marshall and the two exercised a great deal of influence on President Franklin Delano Roosevelt who described Dill as "the most important figure in the remarkable accord which has been developed in the combined operations of our two countries".
