Andre-Marie Ampere was born on 20 January 1775 to Jean-Jacques Ampere, a prosperous businessman, and Jeanne Antoinette Desutières-Sarcey Ampère, during the height of the French Enlightenment. He spent his childhood and adolescence at the family property at Poleymieux-au-Mont-d'Or near Lyon. His mother was a devout woman, so Ampère was also initiated into the Catholic faith along with Enlightenment science. Ampère’s father was called into public service by the new revolutionary government, becoming a justice of the peace in a small town near Lyon. Yet when the Jacobin faction seized control of the Revolutionary government in 1792, Jean-Jacques Ampère resisted the new political tides, and he was guillotined on November 24, 1793, as part of the Jacobin purges of the period.
