Oluf Gerhard Tychsen (1734-1815) was a distinguished Christian Hebraist.[1] A confirmed Lutheran, he devoted his life to Oriental studies, where aside from seminal contributions to Hebrew, Arabic, and Syriac studies, he also made a significant contribution to the decipherment of cuneiform. In 1752, while a student at the Christian Academy in Altona, he also attended the lectures of R. Jonathan Eibeschuetz. From 1755 on, he perused Oriental studies at the University of Jena and then at the University of Halle. In 1759-1760, he served as a missionary to the Jews -- with little success -- travelling through much of Denmark and Germany. He was thrown out of Altona when he attempted to deliver a conversionary sermon in its main Synagogue. Toward the end of 1760 he was appointed Professor of Oriental Languages at the newly established University of Bützov in Mecklenburg. He later served as Chief Librarian and Museum Director at Rostock. He was a prolific author who published some 40 volumes of scholarly studies during his academic career.
