Pierre Clovis François Joseph Claussat (October 12, 1874 – November 9, 1925) was a French politician. He served as the mayor of Châteldon from 1908 until his death in 1925.[2] He also served as a member of the Chamber of Deputies from 1911 to 1925, representing Puy-de-Dôme.[3]
He was born to Joseph Claussat (1846-1910) and Élisabeth Dassaud. He had seven siblings three of whom were: Jean (1872-1916), an infantry commander who died of wounds in Verdun during World War I, Marie "Marguerite" (the mother of painter Josette Bournet) and Élisabeth Eugénie Marie Marguerite Jeanne "Jeanne" (1888-1959) (the wife of politician Pierre Laval and mother of Josée Laval). His father, also a Socialist, had served as mayor of Châteldon from 1881 to 1891.
