Biography of William John Arthur Charles James Cavendish-Bentinck, 6th Duke of Portland (1857-1943)

William was the grandson of Lord [William] Charles Augustus Cavendish-Bentinck, and a great-grandson of the 3rd Duke of Portland. He succeeded to the title when his cousin the 5th Duke of Portland died without heirs in 1879. Educated at Eton, he embarked initially on a military career, serving in, amongst other regiments, the Coldstream Guards.

The 6th Duke held a number of honours, including Chairman of the First Royal Commission on Horsebreeding, President of the Highland and Agricultural Society of Scotland, and Lord Lieutenant of both Caithness and Nottinghamshire. He was also Provincial Grand Master of the Freemasons for Nottinghamshire, as well as being Chancellor of the Order of the Garter, a trustee of the British Museum and Bailiff Grand Cross of the Order of St John of Jerusalem.

An engraved portrait of the duke is available on the National Portrait Gallery website.
