The Passy family is a French political family which had prominent members in 19th Century politics and 20th Century linguistics. Notable members of the family are all descended from Louis François Passy. He was born in Eure in northern France, and members of the family remained within the area for over a century. The five sons of Louis François and Jacquette Pauline Hélène d’Aure held various positions within politics and the military, with two of them joining the Chamber of Deputies and one becoming Minister of Finance. They had one daughter, who married a factory owner from Gisors. The children of the Passy siblings carried on the political and military connection, becoming Deputies or marrying into influential aristocratic families. One member of the family, Frédéric Passy, was awarded the first Nobel Peace Prize, and others became notable phoneticians. Over the years, the family came into possession of three large houses, but they no longer remain within the family.
