High quality portrait of Maximilian Duke Leuchtenberg de Beauharnais, Russian Prince Romanovsky was executed in 1841 and due  to the fully identical quality, composition and manner and on the base of antique backside inscription  was attributed to the hand of German-American portrait painter George Dury (1817 Würzburg, Bavaria -1894, who executed his work probably after similar portrait by famous Munich painter Joseph Carl Stieler ( 1781-1858), although we did not find in on-line this work by  Stieler.

Friedrich Julius Georg Dury (1817–1894) was a well-regarded Bavarian-American portrait artist who worked in both oil and pastel. He was born and educated in Würzburg, Bavaria, and Munich, where he began his career as an artist. He became a bespoke gallery artist in Nashville, Tennessee. He and his family struggled during the American Civil War because Nashville was occupied by Union troops for three years. Soldiers or officers were often billeted with townspeople, and some took the families' food.

After the war, the Tennessee state legislature commissioned several portraits from Dury, including of the late President Abraham Lincoln (assassinated in 1865) and his successor Andrew Johnson, the former vice-president (source-on-line Wikipedia in German).

Dury's work is on display in the US White House, the National Portrait Gallery, the Cheekwood Botanical Garden and Museum of Art, and the Tennessee State Museum.

The sitter of our portrait is Maximilian Joseph Eugène Auguste Napoléon de Beauharnais ( 1817 in Munich - 1852 in Saint Petersburg), the  the 3rd Duke of Leuchtenberg. After his marriage (1839) with Maria Nikolaevna , the daughter of Russian Imperor Nikolai I,  he became Prince Romanovsky.
