Friedrich Wilhelm Blass was a German Protestant classical scholar who lived from 1843 to 1907. During the course of his life, he published extensively on textual criticism of classical authors, such as Demosthenes, Isocrates, Dinarchus, Aeschines, and many others. In the New Testament he published critical editions of the Gospels and Acts, which eventually became the basis of his work Philology of the Gospels. In Indo-European Linguistics and Greek grammar his major contributions included his monograph, Pronunciation of Ancient Greek, his important Grammar of New Testament Greek, and his revision and significant enlargement of Raphael Kuhner’s classical grammar.
