In 1762, in his encyclopaedia The art of the wax producer, engineer Duhamel du Monceau, praises the skills of the Trudons and gives the manufacture as an example.
On the eve of the reign of Louis XIV, M. Trudon established his first family-owned factory which was to bear his name and make the fortune of his heirs.
Claude's son Jacques took over, becoming a grocer and wax producer and joined the Versailles royal court in 1687 as the apothecary and distiller of Queen Marie-Thérèse.
In 1737, Jérôme Trudon, heir of the family, purchased one of the most famous wax producing factories of the times that belonged to Lord Pean de Saint Gilles.
The wax was then treated with the utmost attention: it was washed with the purest water after being filtered with gypsum, guaranteeing the highest quality.
More than one hundred people worked at the time in a very large building – now registered in the French inventory of historical monuments – in the city of Antony, Hauts-de-Seine.
