Samuel Bass (1807–1853) was a Canadian abolitionist who helped Solomon Northup, author of Twelve Years a Slave, attain his freedom. Northup was a free black man from New York who was kidnapped and forced into slavery in the Deep South. At risk of injury and conviction in default of the Fugitive Slave Act of 1850, Bass mailed letters to friends of Northup that initiated a series of events to save him.
