Léopold Javal (1 December 1804 – 28 May 1872)[1] was a French banker, agriculturalist and politician.
His father, Jacques Javal the Younger was one of the richest men in France and established one of the first printed textile mills in the Paris suburb of Saint Denis.
After the war, he took control of the family banking industry, using it to invest in and organise the rail network in Alsace.
Together with the industrialist, Emile Koechlin, he constructed the Mulhouse-Cernay Railroad Line.
He was elected as deputy to the Yonne department in 1857, where he served in the legislature until his death.
