Jean-François Cail

He ended up in the company of Charles Derosne, a manufacturing chemist involved in creating distillation equipment.

The company specialised in making alcohol and confectionery from sugar beet, and building machines to sell for others to follow the process.

It continued to be successful in locomotives and expanded to become an international company, branching especially into engineered structures.

Having become a wealthy man, Mr. Cail built a luxurious townhouse in Paris that is used today by the city government as town hall of the 8th arrondissement.

The tomb lies towards the north-east at the junction of two paths.The main square of his home town Chef-Boutonne is named Place Cail.
