DORNER, ISAAC AUGUST (1809-1884), German Lu theran divine, was born at Neuhausen, Wurttemberg on June 20, 1809. Af ter studying at Tubingen, he travelled in England and Holland, and in 1837 became professor extraordinarius of theol ogy at Tubingen. His Entwicklungsgeschichte der Lehre von der Person Christi (1835-39), an indirect reply to Strauss' Life of Jesus, led to his being invited in 1839 to Kiel as professor ordi narius. There he wrote, among other works, Das Princip unserer Kirche Hach dem innern Verhaltniss seiner zwei Seiten betrachtet (1841). In 1843 he removed to Konigsberg, in 1847 to Bonn, in 1853 to Gottingen and in 1862 to Berlin. In 1867 appeared his valuable Geschichte der protestantischen Theologie (Eng. trans., 1871). His ultimate position as one of the "mediating" theo logians is best seen in his Cliristliche Glaubenslehre (1879--81). The companion work System der christlichen Sittenlehre was pub lished in 1886. He founded and for many years edited the Jalir bucker fur deutsche Theologie. He died at Wiesbaden on July 8, 1884.
