Gottschalk Eduard Guhrauer (15 May 1809 – 5 January 1854) was a German philologist and biographer. He is known principally for his 1842 biography of Gottfried Wilhelm Leibniz and his completion (1853) of Theodor Wilhelm Danzel's biography of Lessing, G. E. Lessing, sein Leben und seine Werke (1850–53, 2 volumes).
He was born in Bojanowo (then in Grand Duchy of Warsaw, now in Poland) and died in Breslau (now Wrocław, Poland).
He studied philology and philosophy in Breslau and Berlin. Under the influence of the English missionary William Ayerst, Guhrauer converted from Judaism to Christianity in 1835. [1] He traveled to Hanover in 1836 and Paris in 1838 to research Leibniz's biography and works. After his return to Germany, he worked as a librarian at the University of Breslau, where he became a professor in 1843.[2] Guhrauer also wrote on Jean Bodin, Joachim Jungius, the Kurmainz (Electorate of Mainz), and the Latin poem Vaticinium Lehninense.
