Édouard Lefebvre de Bellefeuille was born in 1840, in Saint-Eustache, Quebec.

He was a lawyer, journalist, and author who marked the history of Quebec law. In 1860, when he was only twenty years old, he published a "Thèse sur les mariages clandestins". He also published many annotated editions of legal texts and their amendments, namely the Civil Code of Lower Canada (1866, 1879, 1885, 1889, 1891) and the Municipal Code of the Province of Quebec (1879, 1882, 1886) which subsequently became the preferred working tool of several generations of lawyers. In addition to the legal works, he was the author of “Le Canada et les Zouaves pontificaux: mémoires sur l'origine, l'enrôlement et l'expédition du contingent canadien à Rome” (1868) and a “History of the Parish of Saint-Eustache” (1871). He was also one of the founders of the Compagnie de chemin de fer de colonisation du Nord de Montréal, better known as the p'tit train du Nord, and became a member of the board of the Canadian Pacific Railway Company.

He died in 1926.
