Josefine Brunswik von Korompa was born 28 March 1779 in (Holy Roman Empire) to Anton Brunswik von Korompa (1745-1793) and Elisabeth Wankel von Seeberg (1752-1830) and died 1821 (Austrian Empire) of unspecified causes. She married Josef Deym von Střítež (1752-1804) 27 June 1799 in Vienna, Austria. She married Christoph von Stackelberg (1777-1841) 1808 .
In 1799, when she was 20 years old, she was forced to marry Count Josef Deym von Stritetz (c1752-1804), who was nearly 30 years older than her.
In 1799 she made the acquaintance of composer Ludwig van Beethoven (1770-1827). She and her sister Theresia Brunswik von Korompa (1775-1861) first became his pupils. In the following years, Beethoven settled at the Dolná Krupá estate and maintained a close friendship with Josephine, her sister Theresia Brunswik von Korompa (1775-1861) and her brother Franz Brunswik von Korompa (1777-1849). After the death of her husband, Josephine Deym's relation to Beethoven became more intimate, as the fourteen love letters prove, which the composer had written to her during 1804 and 1807. In his letters, Beethoven calls the countess his "only beloved".
In 1810, the Josephine married Baron Christoph von Stackelberg (1777-1841), of Estonian origin, as her second husband. The relationship was very unhappy and the couple separated after only three years, baron von Stackelberg returning to Estonia.
Beethoven's love letters to Josephine were the cause of the assumption, that the countess might be the recipient of the famous letter to the "immortal beloved", which was written in 1812. It also was the cause of the assumption that Beethoven was the father of Minona, Josephine's youngest daughter, who was born in 1813.
