William John Cavendish Cavendish-Scott-Bentinck, 5th Duke of Portland (12 September 1800 – 6 December 1879), styled Lord William Cavendish-Scott-Bentinck before 1824 and Marquess of Titchfield between 1824 and 1854, was a British aristocratic eccentric who preferred to live in seclusion. He had an underground maze excavated under his estate at Welbeck Abbey near Clumber Park in North Nottinghamshire.
He was the second son of William Henry Cavendish-Scott-Bentinck, the 4th Duke of Portland, and his wife Henrietta. He was baptised at St George's Church, Hanover Square, on 30 September. One of nine children, he was known by his second Christian name, John, as all the male members of the family were named William. He was the brother of Charlotte Denison, future wife of John Evelyn Denison, 1st Viscount Ossington.
Cavendish-Scott-Bentinck was educated at home rather than at school. Known as Lord John Bentinck, he served in the army from 1818, entering it as an Ensign in the Foot Guards and later transferred to the 7th Light Dragoon Guards in 1821, where he became a Captain, the 2nd Life Guards in 1823. He reportedly suffered from lethargy due to his "delicate health".
In 1824 he became the Marquess of Titchfield following the death of his elder brother William Henry Cavendish-Scott-Bentinck, and the Tory MP for King's Lynn, a seat traditionally held by a member of his family. He remained an MP until 1826, when he surrendered his seat on grounds of ill-health to his uncle Lord William Bentinck.
From 1824 to 1834 he also held the rank of Captain in the Royal West India Rangers, on half pay. (a sinecure, since this regiment had been disbanded in 1819). After leaving the army, he spent some time in Europe, his health being occasionally poor, including short term memory loss and sciatica.
On 27 March 1854 he succeeded his father as 5th Duke of Portland. Although the title also gave him a seat in the House of Lords, it took him three years to take his seat, not taking the oaths until 5 June 1857. He showed little interest in taking an active role in politics, although he supported the Whigs and Robert Peel. From 1859 until his death he was also Deputy Lord Lieutenant of Nottinghamshire.
The Duke's major building operations and developments at his estate of Welbeck Abbey in which he took an active involvement appealed strongly to the popular imagination. They cost an enormous sum of money and employed thousands of men from the local area, both skilled and unskilled. While there were occasional labour disputes over wages and hours, the Duke was on very good terms with his many employees and earned the nickname "the workman's friend".
The Abbey's kitchen gardens covered an area of 22 acres (8.9 ha), surrounded by high walls with recesses in which braziers could be placed to assist the ripening of fuit. One of the walls, a peach wall, measured over 1,000 ft (300 m) in length.
An immense riding house was constructed, 396 ft (121 m) long, 108 ft (33 m) wide, and 50 ft (15 m) high. It was lit by 4,000 gas jets. Like many other contemporary British aristocrats, the Duke was fond of horses — his stables held 100 horses but he never rode them in his riding house.
When roller skating became popular, the Duke had a rink installed near the lake for the benefit of his staff, whom he encouraged to use it.
The Duke had all the rooms of Welbeck Abbey stripped of furniture, including tapestries and portraits, which he had stored elsewhere. He occupied a suite of 4-5 rooms in the west wing of the mansion which were sparsely furnished. By 1879 the building was in a state of disrepair, with the Duke's rooms the only habitable ones. All the rooms had been painted pink, with bare parquetry floors and no furniture apart from a commode in one corner.
The Duke had a complex of underground rooms and tunnels constructed. The tunnels under the estate were reputed to have totalled 15 mi (24 km), connecting various underground chambers and above-ground buildings. They included a 1,000 yd (910 m) long tunnel between the house and the riding house, wide enough for several people to walk side by side. A more roughly constructed tunnel ran parallel to this for the use of his workmen. A 1.25 mi (2.01 km) long tunnel ran north-east from the coach house, to emerge at the South Lodge, which was supposedly wide enough for two carriages. It had domed skylights and by night was illuminated by gaslight. A tunnel was supposed to have run all the way to Worksop railway station, though there is no evidence for this claim. This and other tunnels are shown on the Ordnance Survey Explorer map of the area, though only the largest can be readily seen on aerial photographs (Multimap).
The underground chambers - all of which were painted pink - included a great hall 160 ft (49 m) long and 63 ft (19 m) which was originally intended as a chapel, but which was instead used as a picture gallery and occasionally as a ballroom. The ballroom reportedly had a hydraulic lift that could carry 20 guests from the surface and a ceiling that was painted as a giant sunset. However, the Duke never organized any dances in the ballroom.
The Duke was very introverted - he did not want to meet people and never invited anyone to his home. His rooms had double letterboxes, one for ingoing and another for outgoing mail. His valet was the only person he permitted to see him in person in his quarters - he would not even let the doctor in, while his tenants and workmen were told never to acknowledge his presence (a workman who saluted him was reputedly dismissed on the spot) and they received all their instructions in writing.
His business with his solicitors, agents, and the occasional politician was handled by post. The Duke maintained an extensive correspondence with a wide-ranging network of family and friends, including Benjamin Disraeli and Lord Palmerston. He is not known to have kept company with any ladies, and his shyness and introverted personality increased over time.
His reclusive lifestyle led to rumours that the Duke was disfigured, mad, or prone to wild orgies. However, contemporary witnesses and surviving photographs present him as a normal-looking man.
He ventured outside mainly by night, when he was preceded by a servant lady carrying a lantern 40 yards ahead of him. If he did walk out by day, the Duke wore two overcoats, an extremely tall hat, an extremely high collar, and carried a very large umbrella behind which he tried to hide if someone addressed him.
If the Duke had business in London, he would take his carriage to Worksop where he had it loaded onto a railway wagon. Upon his arrival to his London residence, Harcourt House in Cavendish Square, all the household staff were ordered to keep out of sight as he hurried into his study through the front hall.
He insisted on a chicken roasting at all hours of the day, and the servants brought him his food on heated trucks that ran on rails through the underground tunnels.
The Duke died on 6 December 1879 at his London residence, Harcourt House. He was buried in a simple grave in Kensal Green cemetery in north London. As his younger brother, Henry William, had died without male issue on 31 December 1870, the title of Duke of Portland devolved upon his cousin, William Cavendish-Bentinck.
The department of Manuscripts and Special Collections, The University of Nottingham holds a number of papers relating to the 5th Duke: the 5th Duke's personal and political papers (Pw K) are part of the Portland (Welbeck) Collection; and the Portland (London) Collection (Pl) contains papers relating to the estate business of the 5th Duke, and to the "Druce Case".
The Portland Estate Papers held at the Nottinghamshire Archives also contain items relating to the 5th Duke's properties.
In 1897 a widow, Anna Maria Druce, claimed that the Duke had led a double life as her father-in-law, a London upholsterer by the name of Thomas Charles Druce, who had supposedly died in 1864. The widow claimed that the Duke had faked the death of his alter ego Druce to return to a secluded aristocratic life and that therefore her son was heir to the Portland estate. However, her application to have Druce's grave in Highgate Cemetery opened to show that the coffin buried in it was in fact empty and weighted with lead was blocked by Druce's executor and the case became the subject of continuing and unsuccessful legal proceedings.
When it was discovered that Druce's children by a former wife were living in Australia, Anna Maria Druce's claims were backgrounded and the case was taken up by George Hollamby Druce from 1903 onwards, who set up a company to finance his legal proceedings in 1905, and in 1907 even instituted a charge of perjury against Herbert Druce, Thomas Charles Druce's younger son, for having sworn that he had witnessed his father's death in 1864. Evidence of a fake burial was given by a witness named Robert C. Caldwell of New York and others, and it was eventually agreed that Druce's grave should be opened. This was done on 30 December 1907 and Druce's body was found present and successfully identified. Two witnesses were charged with perjury, and another witness and Anna Maria were confined to asylums.
