Heinrich Brockhaus (4 February 1804 – 15 November 1874) was a German book dealer and publisher who became a liberal politician.

[1] Heinrich Brockhaus was born into a protestant family in Amsterdam, a principal commercial centre in the Batavian Republic (today the Netherlands) where his father had set up his business in 1802 after falling out with a business partner in the family's former home city, Dortmund.

Heinrich and his younger brother, Hermann Brockhaus (1806-1877) were pupils at the prestigious boys' school run by Carl Lang at Schloss Wackerbarth (Wackerbath castle/manor).

He also took a close interest in authors' rights, a subject in which his involvement continued when he entered into the world of politics.

The second of these marriages placed Heinrich Brockhaus in the unique and sometimes uncomfortable position of being the brother-in-law to the impecunious composer, Richard Wagner twice over.
