Born the son of Lt.-Col. Jean Langevin, Hector-Louis Langevin's first studies were to become a lawyer. In this pursuit he spent time at the Montreal office of George-Étienne Cartier, who would later be a fellow Father of Confederation, before being admitted to the bar.

Although he was accepted to the bar in October, 1850, he had already had a change of direction in his career and since 1847 had been working in the field of journalism. Langevin spent time at various newspapers at different positions. He acted as editor of Mélanges Religieux, contributor to Journal d'Agriculture, political editor of Le Canadien (1872-75), editor of Le Courrier du Canada (1857), and owned his own paper, Le Monde, in 1884.

Langevin started into politics by becoming Mayor of Quebec C. from 1857-61. At the same time he represented the Dorchester electorate in the Canadian Assembly. Langevin served as solicitor-general of Canada East from 1864-66 and post master general, 1866-67. He was also the head of the St.-Jean Baptiste Society from 1861-63 and the leader of the Institut Canadien.

At the Charlottetown Conference he defended Quebec's interests in Confederation. After Confederation he served as secretary of state in John A. Macdonald's first cabinet.
