David Macmillan

David Neil Stirling Macmillan (9 October 1925 – 4 September 1987) was a British historian.

Macmillan was born in Airdrie, Scotland on 9 October 1925. He earned a master's degree from the University of Glasgow in 1949, and a PhD from the University of Sydney, Australia in 1965. He subsequently moved to Trent University in Ontario, Canada, where he was a professor for 20 years. He was seemingly driven by "an all-consuming interest in stamps." His thefts were the subject of news publicity in March 2025. 200 items from the National Records of Scotland were discovered at an auction in London in 1994, at which the historian's estate was to be sold. Some items were still marked with their NRS reference numbers.
