Georges-Louis Leclerc, Comte de Buffon, was an outstanding scientist in 18th-century France with a flair for publicity and grand public debates on a wide variety of topics now called natural science.
Buffon was, according to the late French historian Roger, a man who loved money, power, and women, and who acquired all in great quantity through much intrigue.
(Buffon never put this weapon to use, but his method of constructing concave mirrors is still used today.) But too much of Roger's text is given over to discussing the minutiae of Buffon's arguments with other scientists (in which Buffon was often wrong) and not enough to analyzing the significance of his discoveries and theories.

 George Glazer Gallery - Martinet Buffon Birds
Georges-Louis Marie Leclerc, the Count of Buffon, was a French aristocrat of formidable intellect and achievements, including books on mathematics and natural history.
Buffon’s Histoire Naturelle was his major achievement and an ambitious project characteristic of the 18th-century Enlightenment: a 44-volume encyclopedia attempting to include everything known about the natural world and widely disseminate scientific knowledge.
Decades before Darwin introduced his theory of evolution, Buffon dared to challenge religious thought with empirical observations, suggesting that the earth was older than 6,000 years and that the physical resemblance between humans and apes might be explained by their having a common ancestry.
