Franz Gerhard von Kegelgen (February 26, 1772 - March 27, 1820) was a German painter, noted for his portraits and history paintings. He was a professor at the Academy of Arts in Dresden and a member of both the Prussian and Russian Academies of Arts. His twin brother, Karl von Kegelgen, was also a painter of note. Gerhard von Kegelgen was born at Bacharach am Rhein. After leaving school in 1789, he studied painting in Koblenz. Beginning in 1791, he worked in Bonn, where he painted portraits of Elector Archduke Maximilian Franz of Austria, minister Ferdinand August von Spiegel zum Desenberg, and the Earl of Waldstein. Afterwards, Gerhard von Kegelgen and his brother undertook an educational journey to Rome, Munich and Riga, which was financed by Maximilian Franz of Habsburg. In 1800, Kegelgen married Helene Marie Zoege von Manteuffel. They had three children together. His first son, Wilhelm was born in Saint Petersburg in 1802, and also grew up to become a painter. The other children were Gerhard (born 1806), and Adelheid (born 1808).
