"Johann Jakob Griesbach (4 January 1745 – 24 March 1812), German biblical textual critic, was born at Butzbach, a small town in the state of Hesse-Darmstadt, where his father, Konrad Kaspar (1705–1777), was pastor. Griesbach´s fame rests upon his work in New Testament criticism, in which he inaugurated a new epoch. His solution to the synoptic problem bears his name, but the Griesbach hypothesis has been modernly referred to as the Two-Gospel hypothesis.
