About Jean Lanfray

Lived 1874 – 1906 (aged 31–32). Jean Lanfray was a Swiss worker.

Jean Lanfray (– 26 February 1906) was a French labourer in Switzerland who was convicted of murdering his pregnant wife and two children in a drunken rage on the afternoon of 28 August 1905 in Commugny, Switzerland. It was later revealed by police that he had drunk an excessive amount of wine and hard liquors that morning, along with two ounces of absinthe. However, due to the moral panic against absinthe in Europe at that time, his murders were blamed solely on the influence of absinthe, leading to a petition to ban absinthe in Switzerland shortly after the murders. The petition received 82,000 signatures and absinthe was banned in Vaud shortly thereafter. A 1908 constitutional referendum led to absinthe being banned in all of Switzerland in 1910, and absinthe was banned in most European countries (and the United States) before the outbreak of World War I.

Murders During lunch on 28 August 1905, Lanfray consumed seven glasses of wine, six glasses of cognac, one coffee laced with brandy, two crème de menthes, and two glasses of absinthe after eating a sandwich. He returned home drunk with his father, and drank another coffee with brandy. He then got into an argument with his wife, and asked her to polish his shoes for him. When she refused, Lanfray retrieved a Vetterli rifle and shot her once in the head, killing her instantly, causing his father to flee. His four-year-old daughter, Rose, heard the noise and ran into the room, where Lanfray shot and killed her and his two-year-old daughter, Blanche. He then shot himself in the jaw and carried Blanche's body to the garden, where he collapsed. Finally, on 5 July 1908, Article 32 to the Swiss Constitution was proposed, which would prohibit manufacturing or possession on absinthe in Switzerland. The article was added following a referendum, in which it won by 241,078 to 139,699 votes, and would be effective 7 October 1910. Eventually, similar incidents led to bans on absinthe in every European country (except the United Kingdom, Sweden and Spain) as well as the United States.
