Emilie and her Tutors Emilie not only refused to give up mathematics but she engaged the best known tutors to help her in her study. Emilie not only refused to give up mathematics but she engaged the best known tutors to help her in her study. She also conquered the heart of Voltaire, one of most intriguing and brilliant scholars of this time. Some of Emilie's most significant work came from the period she spent with Voltaire at Cirey-sur-Blaise. For the two scholars this was a safe and quiet haven distant from the turbulence of Paris and court life.

As Voltaire notes "We long employed all our attention and powers upon Leibniz and Newton; Mme du Châtelet attached herself first to Leibniz, and explained one part of his system in a book exceedingly well written, entitled Institutions de physique". However she soon abandoned the work of Leibniz and applied herself to the discoveries of the great Newton.

She was extremely successful in translating his entire book on the principles of mathematics into French. She also added to this book an "Algebraic Commentary" which very few general readers understood.

Samuel Koenig vs. Emilie Du Châtelet As a student her curiosity and stubbornness caused her to place impossible demands on her tutors. As Lynn Osen notes, "Her swift mind outpaced them, her irregular hours disrupted their lives, her rigorous questions were frequently impossible to answer." Such behavior caused her to get into a dispute with another of her tutors, Samuel Koenig, about the subject of the infinitely small. This dispute subsequently ended their friendship and association with one another.

Samuel Koenig vs. Emilie Du Châtelet (cont’d) In 1740 when Emilie's book Institutions de physique was published, Koenig started a rumor that the work was merely a rehash of his lessons with her. Of course this infuriated Emilie and for help she turned to the Academy of Sciences and Maupertuis, with whom she had discussed these ideas long before she engaged Koenig as her tutor.

The knowledgeable scientists of the time were aware of her capabilities of performing the work. However she did not feel that she had received the support she deserved. This was the first time she felt that being a woman really worked against her. The knowledgeable scientists of the time were aware of her capabilities of performing the work.
