Jean-Baptiste Duvoisin

Jean-Baptiste Duvoisin (19 October 1744 – 9 July 1813) was a Roman Catholic priest, theologian and writer, who was Bishop of Nantes from 1802 until his death in 1813.

He was praised by the Napoleon I for being, in theological matters, "a torch of which he did not wish to lose sight," and was often consulted by the Emperor on religious questions.

He received a bachelor's degree from the Sorbonne in Paris and soon joined the university as a professor of theology.

He soon attracted the attention of the first consul, who appointed him bishop of Nantes on 5 July 1802 and gave him his full confidence.

He was the author of several works defending the Catholic Religion against the many hostile attacks made upon it at the time, such as the writings of Baron d'Holbach.
