Joseph-Louis Lambot (born 22 May 1814 in Montfort sur Argens; died 2 August 1887 in Brignoles), is the inventor of ferro-cement, which led to the development of what is now known as reinforced concrete. He studied in Paris, where his uncle Baron Lambot was aide-de-camp to the Duke of Bourbon.
In 1841 he moved to his family's estate of Chateau Miraval in the Department of the Var (Southern France), where he applied himself to agriculture. It is around that time that he started constructing water tanks and troughs using cement mortar (masonry) and iron reinforcement most likely in the form of iron rods, chicken wire (which was invented in Britain in 1844 and used for shipping crates) and possibly barrel bands that were easily available with the arrival of the machine age. In 1848 he constructed his first boat using the same system, which he tested on ponds on the estate. This boat was patented on 30 January 1855 and presented at the 1855 World's Fair in Paris (Exposition Universelle - 1855). Unfortunately, his patents went no further and were superseded by patents of Joseph Monier. The original prototype is preserved at the Museum of Brignoles. Robert Courland describes in his book Concrete Planet that Lambot's boat sank and was preserved in anaerobic mud at the bottom of the lake. The boat was recovered more than a hundred years later.
His birthplace in Montfort-sur-Argens is now "Maison Lambot" BnB.

Fernand Meyssonnier (1931–2008) was an executioner in the last years of French Algeria. He acted as an executioner from 1947 to 1961 and killed more than 200 people.
He is the author of a book "The Executioner's Tale" (Paroles de bourreau : Témoignage unique d'un éxécuteur des arrêts criminels) answering questions about his career as an executioner.He inherited the job of executioner from his father Maurice Meyssonnier in 1947 when he ended compulsory education. His ancestors had been executioners from ages ago. When Algeria became independent from France in 1961, the guillotine was replaced by execution by firing squad.In 1961, shortly before Algerian independence, Fernand Meyssonnier went to Tahiti where he met his future wife with whom he had a daughter, and founded several businesses. After his retirement, he went to metropolitan France. He bought a house in Fontaine-de-Vaucluse where he died on August 8, 2008.
Meyssonnier had been erroneously called the "last (French) executioner alive". In fact, he died the same year as Marcel Chevalier, the last French chief executioner, who served from 1976 to 1977.
