Seventy-six years of life defined the career of Charles-Benjamin de Langes de Montmirail, baron de Lubières, a mathematician and encyclopédiste who navigated the intellectual circles of the Republic of Geneva during the eighteenth century. Although born in Berlin in 1714, his work connected him to the broader European project of systematic knowledge organization through his contributions to the Encyclopédie.
Early Life and Citizenship
Born to François de Lange de Montmirail de Lubières and Marie Calandrini, the younger Lubières emerged from a family displaced by political upheaval. His father, who had departed the Principality of Orange in 1703, sought refuge first in Geneva before settling in Berlin. In 1732, the son secured citizenship within the Republic of Geneva, an status that anchored his later public and intellectual life.
