Lieutenant General Louis de Jean (1706-1764) was one of the great Huguenot military leaders.
In 1752 Louis became a Colonel in the 14th Light Dragoons and in the 6th Dragoon Guards in 1757. He was also appointed second in command to General Wade during the campaign in the Scottish Highlands.
Eventually settling in Dublin, Louis had married Louisa, a burgess of Geneva and had also been elected a director of the French Hospital in 1740. Friends with another Huguenot military leader, Sir John Ligonier, Louis proposed him as another director of the French Hospital.
