Nathan Johnson (ca. 1797-1880) was an African-American abolitionist who sheltered fugitive slaves, most notably Frederick Douglass, and was a successful businessman in New Bedford, Massachusetts. He married Mary Durfee, nicknamed Polly, who was his business partner in their confectionery and catering businesses. In 1849, Nathan followed the Gold Rush to California. Polly died in 1871 and Nathan returned after her death and was a beneficiary of her estate.
The Nathan and Polly Johnson House is on the city's Underground Railroad Tour and has been recognized as a National Historic Landmark.[1]
