Isaac Knapp

Isaac Knapp (January 11, 1804 – September 14, 1843) was a printer and publisher in Boston, Massachusetts.

Knapp was born in Newburyport, Massachusetts to Philip Coombs Knapp and Abigail Remmick; siblings included Abigail Knapp. In 1825 he was proprietor of the Essex Courant newspaper.

With his friend William Lloyd Garrison he produced the anti-slavery Liberator newspaper, 1831-1841. He also co-founded the New England Anti-Slavery Society. His printing office was located on Congress Street (circa 1831) and then on Cornhill.

Garrison and Knapp had a falling out around 1840, and Knapp left the Liberator. In a otherwise favorable eulogy written by Garrison and printed in the Liberator, Garrison implies Knapp became an alcoholic and that his death resulted from this.
