In 1844, he was found guilty of mistreating a maid, which led to her death, and sentenced to one year in prison, but he never had to serve his time.

Due to his work in the worker districts, he suffered from several diseases, including smallpox and encephalitis. He died at the age of 48, after suffering several strokes.

Works Otto von Gerlach published a major rewrite of the old and new testament after Martin Luther, and translated several important texts of the Great Awakening movement from English into German, including works by John Wesley (1703–1791), Richard Baxter (1615–1691), and Thomas Chalmers (1780–1847).
