The son of historical painter Johann Jakob Kirchhoff, he was born in Berlin, and educated there.

He then taught in various colleges until, in 1865, he was appointed professor of classical philology at the University of Berlin,[1] where he remained for the rest of his life.

Kirchhoff's scientific studies covered a wide range in linguistics, antiquities, and Greek epigraphy.

He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1888.
