Louise-Honorée-Françoise Polier de Corcelles, née Louise-Honorée-Françoise de Saussure de Bercher (21 March 1726 – 26 February 1796) was a Swiss amateur artist also known for her correspondence.
Born in Lausanne, Louise Polier de Corcelles was the daughter of David de Saussure, Baron de Bercher, a stockbroker and member of Lausanne's small council, who also served in the French army. Her mother was Angélique Mannlich de Bettens. She was a cousin of the family of Constant de Rebecque. Initially she fell in love with Philippe de Constant, a cousin, but due to local law was unable to marry him. Instead, aged 28, she married Étienne d’Aubonne, who died five years later. Jonathan Polier de Saint-Germain, sgr de Corcelles-le-Jorat, lieutenant baillival de Lausanne, became her second husband in 1767. The couple wintered in Lausanne, summering at the château de Corcelles-le-Jorat. Polier de Corcelles is noted as a pastellist by Isabelle de Charrière in some of her letters; she is also known for having decorated the private theater of her cousin the Marquis de Langallerie. Her correspondence with Salomon and Catherine de Charrière de Sévery has been published.[1] She was the granddaughter of Georges Mannelich.[2]
