August Eisenmenger (11 February 1830 – 7 December 1907) was an Austrian painter of portraits and historical subjects.
At the age of fifteen, Eisenmenger was already a student at the Academy of Fine Arts Vienna and won first prize in drawing.
He didn't find a secure position until he became a student/employee at Carl Rahl's studio in 1856.
He also established a private school where he taught Rahl's style of monumental painting.
