Julian Ersin Memcewicz, a Polish author, born at Skoki, Lithuania, in 1757, died in Paris, May 21, 1841. He was educated in the military academy of Warsaw, and became an adjutant of Czartoryski; but he left the military service in 1788 with the rank of major, and served from 1788 to 1792 in the constituent Polish diet as a deputy of Lithuania. On the outbreak of the revolution of 1794 he fought on the side of Kosciuszko, afterward shared his imprisonment in Russia, and accompanied him in 1797 to America, where he married an American lady. After Napoleon's invasion of Poland he returned to Warsaw (1807), and was appointed secretary of the senate; and after the annexation of Poland to Russia, he became president of the committee on the new constitution. During the revolution of 1830 he was a member of the administrative council. Shortly before the fall of Warsaw he went to Paris, where he spent the rest of his life. His principal works are Spiewy liistiorycznc, or "Historical Songs of the Poles," with historical sketches (Warsaw, 1816), which attained immense popularitv; history of the "Reign of Sigismund III." (1819); "Leb and Sarah," a novel in letters, illustrative of Jewish life in Poland; a historical novel, " John of Tenezyn;" and a collection of admirable tales and fables in the style of Lafontaine. A complete edition of his poetical works was published in 12 vols, in Leipsic in 1840, but his other works, including memoirs, have not yet been collected.

His Notes sur ma captivite a St. Petersburg was published in Paris in 1843.
