Henry Box Brown's Narrative

How do you get a nickname? Some people earn them. Such was the case for Henry "Box" Brown, a man who escaped slavery in a wooden box which measured three feet long, 2 1/2 feet deep, and 2 feet wide. Although conductors of the Underground Railroad like Harriet Tubman are now getting the recognition they deserve, Henry Box Brown pulled off what was at that time the most celebrated escape in the history of American slavery.

In Narrative of the Life of Henry Box Brown, Written by Himself, Brown tells the story of his famed escape and also of the harsh realities of slavery and his effort to make it in the white American and British cultures as a free man.
Added on June 24th: After reading the book I have this to add:
Parts of the Brown's life are repeated again and again. I would encourage interested persons to skip the introduction which gives away parts of the story that you may rather read about in the narrative itself. Read pages 51-96 first and then read other parts of the book if you're still interested.
The narrative clearly gives the reader insight into the lies and hypocrisy that were part and parcel of the slave system in the old south. The introduction and other parts of the book - although they'll repeat a lot of what you already read - will also be valuable to many readers.
