Alexander Herrmann was a German architecture and landscape painter.
Born in Glauchau, Alexander Herrmann studied from 1831 to 1835 at the Academy of Fine Arts and Building School in Dresden with Joseph Thürmer and Gottfried Semper. In 1838 Herrmann went to Munich and in 1839 he moved to Italy, where he stayed mainly in Rome and joined the group of German Romans. Travels from there led Alexander Herrmann to Olevano, Sicily, to Lake Garda, where in 1843 he met the romantic Heinrich Dreber, the Danish landscape painter Niels Frederik Martin Rothe (1816–1880) and Emil Gottlieb Schubackmet, and repeated times to Venice.
Mainly active as an architecture and landscape painter, Herrmann exhibited in the Leipzig Art Association from 1837 to 1845, and in the exhibition of the Berlin Academy in 1842 and 1844 and in the Saxon Art Association.
Schuback made another portrait drawing of him in January 1845. In October of the same year Alexander Herrmann died in Rome and was buried there in the Protestant cemetery.
