Johann Gerhard Oncken

Johann Gerhard Oncken (26 January 1800 - 2 January 1884) was a pioneer German Baptist preacher, variously referred to as the "Father of Continental Baptists", the "Father of German Baptists" and the "Apostle of European Baptists". Oncken, Gottfried Wilhelm Lehmann (1799–1882), and Julius Köbner (1806–1884) were known as the Baptist cloverleaf (kleeblatt). J. G. Oncken helped direct and guide the growth of Baptists throughout Germany and across much of Europe for half a century.
