Alexander originally Sándor von Wagner (April 16, 1838 - January 19, 1919)
Wagner was born in Pesth. After graduating from the Real-Gymnasium in his hometown at the age of nineteen, he entered the Academy of Fine Arts at Vienna, where he was a student of Henrik Weber. The following year, he switched to the Royal Academy of Fine Arts and was taught by Professor Karl von Piloty from 1856 to 1864. From 1869 to 1910 he was professor in history painting at the Munich Academy. His themes were history paintings and Hungarian life scenes in particular. A portrait of Von Wagner painted by Franz Lachner belongs to the collection of the Gebrüder-Lachner-Museum in Rain since 2003. One of his pupils was Pál Szinyei Merse.
Von Wagner died in Munich, where he is buried in the Old Southern Cemeterey.
