Catherine Joséphine "Katia" Krafft (née Conrad; 17 April 1942 – 3 June 1991) and her husband, Maurice Paul Krafft (25 March 1946 – 3 June 1991) were French volcanologists and filmmakers who died in a pyroclastic flow on Mount Unzen, Nagasaki, Japan, on 3 June 1991. The Kraffts became well known as pioneers in the filming, photographing, and recording of volcanoes, often coming within feet of lava flows. Their obituary appeared in the Bulletin of Volcanology. Since their deaths, their work has been featured in two documentary films by Werner Herzog, Into the Inferno (2016) and The Fire Within: A Requiem for Katia and Maurice Krafft (2022), and a further film, Fire of Love (2022), depicted their lives, relationship and careers using their archived footage.

John Joseph Joubert IV (July 2, 1963 – July 17, 1996) was an American serial killer executed in Nebraska. He was convicted of murdering three boys: one in Maine, and two in Nebraska.

Joseph Gleydson Vacher (16 November 1869 – 31 December 1898) was a French serial killer and necrophile, sometimes known as "The French Ripper" or "L'éventreur du Sud-Est" ("The South-East Ripper") owing to comparisons to the more famous Jack the Ripper murderer of London, England, in 1888. His scarred face and plain, white, handmade rabbit-fur hat composed his trademark appearance. He killed 11 to 27 people, many of whom were adolescent farm workers, between 1894 and 1897.
