Group Captain James Stagg (1900-1975)

Meteorologist

James Stagg was a graduate of the University of Edinburgh. He joined the British Meteorological Office in 1924 where he later became superintendent at the Kew Observatory.  He was also leader of a British Polar Expedition to the Arctic. In 1944 Group Captain James Stagg was appointed meteorological adviser to General Eisenhower and the other allied commanders. He worked with the British and American forecasting centres providing data to military planners. It was his advice on weather conditions that led to the postponement of the D-Day landings from 5 to 6 June. After the War this significant contribution was recognised on both sides of the Atlantic. In later years he was elected a fellow of the Royal Society of Edinburgh and president of the Royal Meteorological Society. On the 75th anniversary of D-Day a memorial plaque was unveiled at Dalkeith Library.

You can find out more about his role in the article 'How a weather forecast made history - the D-Day Landings' and related resources on the Royal Meteorological Society's website.

In 1911 James Stagg, 10, was enumerated with his family at 153 High Street, Dalkeith. The census return for that district records that he was at school. The household included his brother, Alexander, aged 2, and his grandfather, James Martin, 68, plasterer, working in the building trade. The 1911 census collected data on the 'particulars of marriage'. This shows that James' parents, Alexander and Helen, had been married for 12 years, that they had two children born alive and two children still living.
