Augustin Sesmat

Augustin Sesmat (April 7, 1885 Dieulouard -- December 12, 1957) was a French mathematician and logician. He was professor of history and criticism of science at the Institut Catholique de Paris in the 1930s. He was probably the first person to discover the logical hexagon, thus solving a problem posed by Aristotle.
