In his 1906 work, "Das Sexualleben unserer Zeit in seinen Beziehungen zur modernen Kultur" ("The Sexual Life of Our Time in its Relation to Modern Civilization"), Iwan Bloch, a German-Jewish physician, entreated elderly homosexuals to self-disclose to their family members and acquaintances. In 1914, Magnus Hirschfeld revisited the topic in his major work "The Homosexuality of Men and Women", discussing the social and legal potentials of several thousand homosexual men and women of rank revealing their sexual orientation to the police in order to influence legislators and public opinion.
