Felix Adler was a German American professor of political and social ethics, rationalist, influential lecturer on euthanasia, religious leader and social reformer who founded the Ethical Culture movement.
Felix Adler was born in Alzey, Grand Duchy of Hesse, Germany, the son of a rabbi, Samuel Adler, a leading figure in European Reform Judaism. The family immigrated to the United States from Germany when Felix was six years old so that his father could accept the appointment as head rabbi at Temple EmanuEl in New York.
