Alan Davidson, British soldier, historian, and author (b. 1924)
Alan Eaton Davidson CMG (30 March 1924 – 2 December 2003) was a British diplomat and writer best known for his writing and editing on food and gastronomy.

After leaving Queen's College, Oxford in 1948, Davidson joined the British diplomatic service, rising through the ranks to conclude his career as ambassador to Laos, from 1973 to 1975. He retired early and devoted himself to full-time writing about food, encouraged by Elizabeth David and others. He published more than a dozen books between his retirement and 2002, but his magnum opus was The Oxford Companion to Food, a work of more than a million words, which took twenty years to complete and was published to international acclaim in 1999.
