Otto Walper

Otto Walper (also Latin Otho Gual(t)perius; January 1, 1543 – December 28, 1624) was a German theologian and philosopher.
Otto Walper was born in Rotenburg an der Fulda, and studied at the University of Marburg, where he later became the main professor of Greek (from 1582) and Hebrew (from 1585), having received a Ph.D degree at the University of Basel in 1582. Being a Lutheran, Walper left Marburg in 1593 after the ruling Prince of Hesse-Kassel (to which Marburg belonged) converted to Calvinism and professors at the territory's university were expected to follow suit. Walper went to Lübeck, where he became principal of the Catharineum Latin school.
Walper's Greek grammar was reprinted several times and remained in popular use as a school grammar until the 18th century. He was also one of the first Christian authors to write a Hebrew grammar.
He had a son and a daughter by his wife Zeitlose Orth. He died in Lübeck, aged 81.
