"David ben Meir Cohen Friesenhausen (1756\u20131828) was a German-Hungarian astronomer, maskil, mathematician, and rabbi. Friesenhausen was one of the first proponents of Torah im Derech Eretz, a philosophy of Orthodox Judaism that formalizes a relationship between traditionally observant Judaism and the modern world. He proposed a dual curriculum of Jewish and secular studies for all rabbinic candidates, a radically innovative idea at that time. Friesenhausen wrote Mosedot Tebel and Kelil Heshbon."@en .
