Mr Adrien Firmin Chaboisson was born at Preuilly-sur-Claise, Indre-et-Loire, France on 25 September 1886.
He was the son of Jacques Chaboisson (1853-1929) and Evelina Merigon (1860-1931); he had two known siblings, elder brothers Leon (b. 1882) and Raoul (b. 1883).
Having completed military service Chaboisson began a career working at luxurious hotels and wound up being employed in London. He was shown on the 1911 census as a visitor to 19 Kennington Park Gardens, London SE, the home of a French family, the Guillerands; he was described as an unmarried cook.
When he signed-on to the Titanic on 6 April 1912 he gave his address as c/o Gatti, London. His actual address was still 17 Kennington Park Gardens and the Titanic was his first ship. As a member of the restaurant he was employed and therefore paid by Mr Gatti; also serving aboard was a friend and colleague, Pierre Villvarlange.
During the sinking there were reports that the largely continental staff of the restaurant, mainly French, Italian, Swiss, German and Belgian, were herded to their quarters by stewards and kept there. Indeed, only three from the staff survived, two of whom were the female cashiers.
Adrien Chaboisson died in the sinking and his body, if recovered, was never identified.
