Lord Frederick William Charles Nicholas Wentworth Hervey (/ˈhɑːrvi/)[1] (26 November 1961 – 26 January 1998)[a] was a British aristocrat and political activist.

Lord Nicholas's father was Victor Hervey, 6th Marquess of Bristol (1915–1985) of Ickworth House in Suffolk, a very wealthy aristocrat once described as "Mayfair's No.

1 Playboy," in a series of "life story" articles he wrote after serving a jail sentence for jewel robbery, a crime he claimed he had committed for a dare.

Lord Nicholas's mother, his father's second wife whom he had married in 1960 being her first husband,[6] was Lady Juliet Wentworth-Fitzwilliam, the only child and sole heiress of the very wealthy 8th Earl Fitzwilliam (d.1948), who died in a small aircraft crash when she was aged 13.

Also killed was his intended second wife, Kathleen, Marchioness of Hartington, a daughter-in-law of the Duke of Devonshire and a sister of US President John F. Kennedy.

Through the League, which his father had subsidised for many years, he became friendly with Gregory Lauder-Frost, who introduced him to numerous right-wing conservative activities.

One such event, on 25 September 1989, was the Western Goals Institute dinner at Simpson's-in-the-Strand, chaired by Lord Sudeley, for the President of El Salvador, Alfredo Cristiani, and his inner cabinet.

His mental health worsened when it was discovered that the principal heirs of the unentailed estate of his father, who had died in 1985, were not Nicholas and his elder brother, the latter who had, however, inherited Ickworth House and a large fortune, but rather his third wife and her young children.

His landlady said that he "drew no shred of comfort from the high rank and great riches to which he was born" and that "he was a recluse, in the sense that he was heavily sedated and slept all day – a typical schizophrenic.
