Pierre de Sales Laterrière

Pierre de Sales Laterrière (French pronunciation: [pjɛʁ də sal latɛʁjɛʁ]; 1743 or 1747 – 14 June 1815), was an adventurer who left France in 1766.

He was inspector and director of the ironworking Forges du Saint-Maurice and seigneur of the municipality Les Éboulements in New France (Canada).

In 1776, the director of the ironworks, Christophe Pélissier (businessman), was arrested by the British for supplying weapons and ammunition to the American army that was advancing towards Quebec.

Despite public opinion and criticism from the clergy, this free thinker, defender of midwives and freemason lived unmarried with Marie-Catherine until they finally married in 1799, after the death of her first husband.

Imprisoned by the British Governor Frederick Haldimand on the day following the American Invasion, he was then exiled in Newfoundland from 1782 to 1783, following a (probably) false charge of treason.
