Jules Destrée (French: [dɛstʁe]; Marcinelle, 21 August 1863 – Brussels, 3 January 1936) was a Walloon lawyer, cultural critic and socialist politician. The trials subsequent to the strikes of 1886 determined his commitment within the Belgian Labour Party. He wrote a Letter to the King in 1912, which is seen as the founding declaration of the Walloon movement. He is famous for his quote "Il n'y a pas de Belges" (There are no Belgians), pointing to the lack of patriotic feelings in Flemings and Walloons, while pleading for some kind of federal state.

Germaine Berton (7 June 1902, in Puteaux – 6 July 1942, in Paris) was a French anarchist and trade unionist. She is known for the murder of Marius Plateau, an editor for the Action Francaise journal and a leader in the royalist organisation Camelots du Roi, in January 1923. Germaine Berton was defended by Henri Torrès during her trial and surrealists have used her mugshot in a number of art pieces. Despite confessing, Berton was acquitted on 24 December 1923.
Berton stopped engaging with anarchist organizations following a subsequent arrest in 1924. In 1925, Berton married Paul Burger, a painter before leaving him in 1935 for René Coillot, a printer. She died in 1942 due to an intentional overdose.

Martin Dumollard (June 22, 1810 − March 8, 1862) was a French serial killer condemned to the guillotine after having been arrested and charged with the deaths of maids from 1855 to 1861. His victims were approached in Lyon by Dumollard, who offered them a nice house in Côtière. Convinced, they would eventually follow him and, during their wanderings on foot, he attacked them. All twelve assaults or attempted assaults occurred in the late 1850s and early 1860s until that of Marie Pichon on May 28, 1861. He was quickly arrested, along with his wife and accomplice, Marie-Anne Martinet, who stole the personal belongings and used them for resale. Their trial took place from January 29 to February 1, 1862: Dumollard was sentenced to death and his wife, twenty years of penal labour. This affair, which preceded that of Joseph Vacher by about thirty years, had a great repercussion in France; it is often considered one of the first cases of a serial killer in France. Dumollard is notably mentioned in Les Misérables by Victor Hugo.

Sir Joseph Beecham, 1st Baronet (8 June 1848 – 23 October 1916) was a British businessman.

He was responsible for Beechams' factory and office in Westfield Street, St. Helens, being built in 1885. A factory was subsequently opened in New York followed by more factories and agencies in several other countries. The increasing demands placed on him by his father's business meant he had to step down from his position as the parish organist of St John the Evangelist, Ravenhead.
Beecham was the proprietor of the Aldwych Theatre in London, a justice of the peace for Lancashire and was mayor of St. Helens between 1889 and 1899 and again from 1910 to 1912. He was made a baronet, of Ewanville in the Parish of Huyton in the County Palatine of Lancaster, in 1914. He was invested as a Knight of the Order of Saint Stanislaus by Tsar Nicholas II. Beecham was a patron of the arts and purchased a number of paintings by J. M. W. Turner. Beecham married Josephine Burnett in 1873.
