(Born: c1601; Died: 1640) French woman mineralogist.
Martine de Bertereau, an expert dowser, and her husband Jean de Chastelet, Baron de Beausoleil et d'Auffenbach, an expert in mineralogy and mining, made a name for themselves in 17th century Europe. Using a variety of hazel branches and metal rods, Martine reportedly located rich mineral and water deposits. But when the infamous French Cardinal Richelieu caught wind of exactly how Martine was prospecting, he pitched the couple into prison, along with two of their kids.

Work on mining and mineralogy authored by the only documented woman mineralogist of her time. She married Jean Du Chatelet, Baron Beausoleil, inspector of mines of the German empire and together they visited the mines of South America, Hungary and Germany. When Beausoliel secured the authorization to survey the whole of the French territory for the discovery of mines and minerals, his wife accompanied him in his travels throughout France. This book is the outcome of their work. Written in the form of an appeal to Cardinal Richelieu to open and operate the French mines, it contains a long list of these mines, discusses all minerals found, speaks of different sciences to be studied by a mining expert. Ultimately, the author was imprisoned by order of Richelieu, because of suspicion of witchcraft in the use of divining rods. She died in prison.
