Joachim Camerarius

Joachim Camerarius, a learned nobleman, was born in Bamberg, 12 April 1500. He studied Greek in Leipzig in his youth alongside the "exercises of nobility," and became close friends with Melancthon. Camerarius organized a school at Nuremberg, and was then called to Württemberg as one of the first professors at the new University of Tübingen. He later returned to Leipzig, where he was professor of Greek and Latin. He died there 17 April 1774. From Camerarius came the Latin hymn "In tenebris nostrae et densa caligine mentis" (sometimes attributed to Melancthon), which Paul Eder translated into the German hymn: "Wenn wir in höchsten Nöten sein."
