Martine de Bertereau, also known as Baroness de Beausoleil, was the first recorded female mineralogist as well as mining engineer along with her husband, Jean de Chastelet. She traveled extensively throughout Europe in search of mineral deposits and fresh ground water under the employment of various nobles and royals. During the reign of the French King, Luis XIII, Martine and her husband surveyed the sites of potential mines in France. During one of their mining expeditions Martine and her family were accused of witchcraft and fled to Hungary. Later, Martine, her husband and oldest daughter were arrested and eventually died in prison sometime after 1642. During her life, she produced multiple pieces of literature derived largely from the Roman engineer Vitruvius's book on architecture, De architectura. Her writings describe the use of divining-rods, similar to dowsing, as well as other renowned scientific ideas. Martine de Bertereau was not forthcoming about her use of different scientific ideas, and preferred the public to believe she was using magic, or renowned ancient scientific ideas. Her success came from her development in the understanding of the geologic world around her. It is uncertain of her reasoning behind the decision to lie about her actual means of success. Her literature provides a unique glimpse into the craft and skills required to mine in the seventeenth century.[1]
