Edward Westermarck

Born in Helsinki in 1862, Edward (Edvard) Westermarck became one of Finland’s most internationally recognized scholars. He worked across social anthropology, sociology, and philosophy, and is especially remembered for studying the history of marriage, moral ideas, and the incest taboo.

His best-known book, The History of Human Marriage (1891), challenged older theories about early human society and argued that pair-bonding and marriage had deep historical roots. He later expanded his work on ethics in The Origin and Development of the Moral Ideas, connecting moral judgments to human emotions and social life.

Westermarck also helped shape sociology as an academic field in both Finland and Britain, and his ideas continued to echo long after his death in 1939. Today he is still discussed for his wide-ranging scholarship and for the psychological idea later called the Westermarck effect.
