Biography
About Franz Rosenzweig.
Franz Rosenzweig was born in 1886 in Kassel, Germany, into an assimilated Jewish family. He studied philosophy and history, becoming deeply immersed in German idealism, particularly Hegel. By 1913, influenced by his friend Eugen Rosenstock-Huessy, he had decided to convert to Christianity, but he wanted to enter Christianity as a Jew, not as a mere pagan. He attended Yom Kippur services in a small Orthodox synagogue in Berlin, intending it as a farewell. Instead, something happened there that he never fully explained; he emerged determined to remain a Jew and to discover what Judaism could mean for a modern person. World War I found him serving on the Balkan front, where he began writing The Star of Redemption on postcards sent home to his mother. The book, completed in 1919, is a dense philosophical work that rejects the totalizing systems of German idealism.
