Bern, Joseph, Polish general, was born in 1795 at Tarnow, Galicia, and served first in the French army in their expedition against Russia in 1812. After taking part in the Polish insurrection of 1830 he withdrew to Paris, where he gained his livelihood by teaching. In 1848 he joined the Hungarians and won several battles against the Austrians and Russians. After the defeat of Temesvar he escaped to Turkey, where he adopted the Mohammedan faith and became a pasha. He died in 1850 at Aleppo, whither he had been sent to suppress an insurrection of the Arabs.
