Biography

Edme Mariotte was the youngest son of Simon Mariotte, administrator at the district Til-Châtel (†16 Augustus 1652), and Catherine Denisot (†26 September 1636 due to plague). His parents lived in Til-Châtel

 and had 4 other children: Jean, Denise, Claude, and Catharine. Jean was administrator in the Parlement of Paris from 1630 till his death in 1682. Denise and Claude, both married, stayed in the Dijon region, where as Catharine married Blaise de Beaubrieul, advisor of king Louis de XIV. Catherine and Blaise lived in the same street, perhaps on the same address, where Jean lived. The early life of Edme Mariotte is unknown. His title "Sieur de Chazeuil" was probably inherited from his brother Jean in 1682. It refers to the estate of his father, which was first given to Jean. This estate was in the region Chazeuil. It is not clear whether Mariotte spent most of his early life at Dijon

. The address on a letter found in the Leibniz archive shows that Edme lived in the rue de Bertin-Poirree, near the chapel of the guild of the goldsmiths in the rue des Orfevres in 1677. Perhaps he lived together with Jean and the couple Catherine and Blaise de Beaubreuil. Leibniz wrote that Edme stayed at Mr. Beaubrun's address, but probably he meant Beaubreuil, which sounds quite similar. Edme quitted the Academy in 1681 and died on the 12th of May 1684.
