Frederick Douglass was the only Black man who attended the first Woman’s Rights Convention at Seneca Falls, NY.
Frederick Douglass was born a slave, and learned to read and write at 12 years old; he then taught other slaves to read as well. At 38, he escaped slavery by pretending to be a sailor; then he wrote many articles for anti-slavery magazines and newspapers.
He was an amazing public speaker, changing minds by his use of reason and passion. Douglass supported the women's rights movement as well - very rare for men and men of color in this period. “Frederick Douglass was at the forefront of the U.S. abolitionist movement in the 19th century, and he is particularly well known for his autobiography, "Narrative of the Life of Frederick Douglass, an American Slave, Written by Himself" (1845; revised and completed in 1882 as "Life and Times of Frederick Douglass"), which gives an account of his escape from slavery and his pursuit of literacy, education, and independence. The work established Douglass as the leading African American man of letters of his time.” Brittanica Encyclopedia
