German portrait painter. She was born into a family of painters of Polish noble origin. Her father, Georg Lisiewski (1674-1751), taught her painting and also taught her younger sister Anna Dorothea and her brother Christoph Friedrich (1725-1794). She later studied with the painter Antoine Pesne and learned his style of painting. In 1757, she was appointed as court painter by Frederick Augustus of Anhalt-Zerbst. During her ten year stay at the court, she painted a gallery of forty ladies. Later, she moved to the ducal court in Brunswick, where she received a generous grant from Duchess Philippine Charlotte of Brunswick-Wolfenbüttel. In 1741, Anna Rosina married the Prussian court painter David Matthieu (1697-1755) and became the stepmother of Georg David Matthieu. After David's death, she married in 1760 to Louis de Gasc, who was a friend of Gotthold Ephraim Lessing. She had two children with him. Her younger sister (Anna Dorothea Therbusch) was also a portrait painter. //
