David Friedländer
David Friedländer was born in Königsberg and settled in Berlin in 1771. There he fashioned himself as a disciple of Moses Mendelssohn and became an advocate for the emancipation of Prussian Jews. In an infamous open letter to Probst Teller of the Lutheran Church in Berlin, he asked if Jews could join the Lutheran Church on the condition that they did not have to believe in the divinity of Jesus, as a means of gaining civic equality. The plan failed. He aimed at educational reforms and founded the Jewish Free School in 1778. He translated works by Moses Mendelssohn, translated a prayer book from Hebrew to German, and wrote textbooks to be used in liberal Jewish schools.
