His father, Thomas Waddington, took control of the family business ventures in France after his brother William's death in 1818. Senator Waddington's mother was Anne, daughter of William Chisholm MD, son of The Chisholm (qv. Roderick Chisholm, 21st Chief of Chisholm).
Politics and writing
Waddington was elected a Deputy to the French Parliament in 1876, where his industrial experience was valued. He sat on the Centre-Left benches until 1891 when he was elected as Senator for Seine-Inférieure. He was returned to the Senate in 1900 and in 1909, where he served until his death in 1913.
He wrote Louis XV et le renversement des alliances (1896), and La guerre de sept ans: histoire diplomatique et militaire (five volumes, Paris : Firmin-Didot et cie, published 1899–1914).
