He was born in
Vienna. At the age of fifteen, Eisenmenger was already a student at the
Academy of Fine Arts Vienna and won first prize in drawing. In 1848, his financial circumstances forced him to leave the Academy. He didn't find a secure position until he became a student/employee at
Carl Rahl's studio in 1856. In 1863, he started as a drawing teacher at the Protestant School in Vienna. He later became a professor at the Academy in 1872. He also established a private school where he taught Rahl's style of monumental painting.
Rudolf Ernst was one of his best known pupils there. He died in Vienna in 1907. In 1913, a street in Vienna's
Döbling district was named after him. Later, that street was removed for an industrial site and a new street was dedicated to him in the
Favoriten district in 1959. One of Eisenmenger's sons,
Victor Eisenmenger, was the personal physician to
Archduke Franz Ferdinand. ==Major works ==
