Caspar René Gregory (November 6, 1846 – April 9, 1917) was an American-born German theologian.
[3] In 1873, he decided to continue his studies at the University of Leipzig under Constantin von Tischendorf, to whose work on textual criticism of the New Testament he had been referred by his teacher Ezra Abbot.
[citation needed] In June 1901, he received an honorary doctorate of Divinity from the University of Glasgow.
[6] On August 11, 1914, Gregory, who had been a citizen of Saxony since 1881, enlisted in the German Army as its oldest wartime volunteer.
He organized biblical manuscripts into a classification system (Die griechischen Handschriften des Neuen Testaments, 1908) which continues to be in use throughout the scholarly world today.
