Denis (sometimes Didier) Henrion, was a French mathematician born at the end of the 16th century in France.^[1] He co-edited the works of Viète. He died around 1632 in Paris.

Contributions

Henrion wrote a tract concerning logarithms.^[2]

He translated Euclid's Elements from Latin into French.

He published Problemata nobilissima duo (Paris, 1616), a book against Marin Ghetaldi and attacking Viète and Regiomontanus. Later reorganized, the book was republished by its author.
