“Banning Jews from Academic Positions” issued by the Prussian State Ministry [Prussia / Present-day Germany, Poland]: “Because the ordinance […] that local Jews who have shown a great deal of talent in academic teaching positions are to be allowed to pursue them, has caused a lot of confusion in its execution, it is therefore henceforth repealed.”
