Edward Westermarck (1862–1939) grew up in an academic Swedish-speaking family in Helsinki, Finland. He became, at the London School of Economics, Britain’s first professor of sociology. Very famous in his own day for taking an evolutionary view of marriage and morality, he published (in English) many works: The History of Human Marriage (1891), a critical success and a bestseller, quickly translated into many other languages; The Origin and Development of the Moral Ideas (1906; 1908); Marriage Ceremonies in Morocco (1914); Ritual and Belief in Morocco (1926); Ethical Relativity (1932); and Christianity and Morals (1939). He also taught philosophy in Finland, in Helsinki and Turku.
