William Still was one of the most important people who took part in the Underground Railroad. William had been just a boy when he first helped a fugitive escape. All he had known about the man was that he was being hunted by slave catchers, but William was determined to help him.
From 1844 to 1865, William Still helped at least 60 enslaved African-Americans escape every month. As a result of this, William became known as the "Father of the Underground Railroad". William interviewed the slaves and during one of his interviews realized that the fugitive slave he was questioing was his lost brother, Peter, who'd been sold to a different owner when they were younger.
After the abolition of slavery, William published the interviews he did into his book, "Underground Railroad". The book was an important factor to the literature and history of African-Americans for being able to document the history of abolitionists and former slaves. In 1876, 'Still placed the book on exhibit at the Philadelphia Centennial Exposition' to remind visitors of the history of slavery in America.
