Fulgence Bienvenüe (French pronunciation: [fylʒɑ̃s bjɛ̃v(ə)ny]; 27 January 1852 – 3 August 1936) was a French civil engineer, best known for his role in the construction of the Paris Métro, and has been called "Le Père du Métro" (Father of the Metro).
A native of Uzel in Brittany, and the son of a notary, in 1872 Bienvenüe graduated from the École Polytechnique as a civil engineer and the same year he began working for the Department of Bridges and Roads at Alençon. His first assignment was the construction of new railway lines in the Mayenne area, in the course of which his left arm had to be amputated after being crushed in a construction accident.
