A Darwinian Murder: The Role of the Barré-Lebiez Affair in the Diffusion of Darwinism in Nineteenth-Century France

Most studies on the reception of Darwinism in France focus on the scientific community. This essay investigates the popular press. Widely discussed in French newspapers in 1878, Darwinism was connected with a sensational murder case in which two well-educated young men, Aimé Barré and Paul Lebiez, killed an elderly woman. Before his arrest, Lebiez had given a public lecture on the Darwinian “struggle for life.” Competing factions of the press explicitly linked the case with Darwinism to advance either conservative or republican political agendas, which brought Darwinism into the public eye. This essay argues that Charles Darwin’s instrumentalization was decisive in spreading his theory in French society. That same year, the Academy of Sciences elected Darwin to membership after six failed attempts.
