Henri Louis Baudrier

Henri-Louis Baudrier (; 29 May 1815 – 17 June 1884) was a French bibliographer and magistrate, and the co-author of Bibliographie lyonnaise: recherches sur les imprimeurs, libraires, relieurs et fondeurs de lettres de Lyon au XVIe siècle par le Président Baudrier, publiées et continuées par J. Baudrier, (; "J.) Baudrier" refers to Henri-Louis Baudrier's son, (1860–1915). The work focused on the bookselling and publishing industry of 16th-century Lyon, featuring entries on more than 2,000 individuals, many of whom were printers, bookbinders, and booksellers based in Lyon.

Born into a family of magistrates in Lyon, Baudrier embarked on his judicial career in 1846 as a substitute judge, though he was dismissed just two years later. By 1849, he had been reinstated as a magistrate, eventually rising to the position of Court Counsellor in 1856 and President of the Chamber in 1869.

A bibliophile and avid book collector, Baudrier amassed a library of more than 8,000 volumes, primarily composed of 15th and 16th-century Lyonnais imprints. He died in Paris in 1884.
