De Saussure family

The De Saussure family is a family from the Geneva patriciate of Huguenot origins hailing from Lorraine, France but being settled in Switzerland since 1556. An American branch was established in South Carolina in the 18th century by Henri de Saussure; among his descendants were Chancellor Henry William de Saussure and US Senator William F. De Saussure.

History
The family originally hails from Saulxures in the Lorraine region of France. During their service as falconers to the duke he ennobled them in 1506. Due to religious persecution for being Huguenot they emigrated to Lausanne and Geneva, where they became citizens in 1556 respectively 1636.

Swiss branch
In Switzerland they soon became politically and socio-economically active holding a variety of public offices. Théodore de Saussure became the mayor of Geneva, his son Nicolas de Saussure, a politician. Horace-Bénédict de Saussure, an 18th century naturalist, was probably the most notable, his portrait was on the 20 Swiss Francs bill series which were in circulation from 1979 to 1995. His great-grandson Ferdinand de Saussure (1857-1913) was an important linguist and semiotician. More recently, a descendant of this branch, is Jacques de Saussure, who was a part-owner in private bank Pictet Group and current owner of the hôtel particulier of the family.

American branch
Henri de Saussure (anglicized to Henry de Saussure, d. 1761), a scion of the Lausanne branch of the family, emigrated from Vaud in the Old Swiss Confederacy settling near Charleston, South Carolina. The four sons of Henri fought in the American Revolutionary War with only his son Daniel surviving. Daniel was the father of Henry William de Saussure, d. 1839, a notable jurist in the early days of the American republic. There are still several descendants living with the current spelling being DeSaussure, deSaussure, or Desaussure in the United States. Louis D. DeSaussure, d.1888, was a slave trader.
