  • 1771: Mathematician and logician Joseph Diez Gergonne born. He will contribute to the principle of duality in projective geometry, by noticing that every theorem in the plane connecting points and lines corresponds to another theorem in which points and lines are interchanged, provided that the theorem embodied no metrical notions.
