The business created by Mr. Hippolyte FORMAT

The arrival of the first train at Marseille’s St Charles station dates back to 1848 in France. At this time, Marseille is experiencing one of its most important periods of economic prosperity, due, in particular to the trade of exotic products. The hills are scattered with grist mills. Semolina and flour milling activities are developing rapidly. Marseille is increasingly turning towards importation and exportation and goods are transported in sacks requiring handling services.

This is the very first known activity of the business created by Mr. Hippolyte FORMAT in 1860, which would also rapidly begin to propose cleaning services in the grist mills. Years later this company would become the Onet Group.
