Extinct barony in the Peerage of the United Kingdom
Baron Playfair, of St Andrews in the County of Fife, was a title in the Peerage of the United Kingdom. It was created on 3 September 1892 for the scientist and Liberal politician Sir Lyon Playfair. He was succeeded by his only son, the second Baron. The second Baron was a Brigadier-General in the British Army. The second Baron's only son, the Hon. Lyon George Henry Lyon Playfair (1888-1915), was a Captain in the Royal Field Artillery and was killed in action in the First World War, unmarried. Consequently, the title became extinct on the death of the second Baron in 1939.
