Lobegott Friedrich Constantin (von) Tischendorf (18 January 1815 – 7 December 1874) was a world-leading biblical scholar in his time. In 1844 he discovered the world's oldest and most complete Bible dating from 325, with the complete New Testament not discovered before. This Bible is called Codex Sinaiticus, after the St. Catherine's Monastery at Mt. Sinai, where Tischendorf discovered it...His magnum opus was the "Critical Edition of the New Testament." The great edition, of which the text and apparatus appeared in 1869 and 1872, was called by himself editio viii; but this number is raised to twenty or twenty-one, if mere reprints from stereotype plates and the minor editions of his great critical texts are included; posthumous prints bring the total to forty-one. Four main recensions of Tischendorf's text may be distinguished, dating respectively from his editions of 1841, 1849, 1859 (ed. vii), and 1869–72 (ed. viii). The edition of 1849 may be regarded as historically the most important, from the mass of new critical material it used; that of 1859 is distinguished from Tischendorf's other editions by coming nearer to the received text; in the eighth edition, the testimony of the Sinaitic manuscript received great (probably too great) weight. The readings of the Vatican manuscript were given with more exactness and certainty than had been possible in the earlier editions, and the editor had also the advantage of using the published labours of his colleague and friend Samuel Prideaux Tregelles.
