Why Thomas "Blind Tom" Wiggins was the most famous black musician of the 1800s

Very recommendable! 

Let's not forget it was the southern slave owner who bought the family of the little blind boy and discovered and promoted his talents. He allowed him to travel the world to perform his music to the delight of many in the audience. Who knows whether the blind boy would have a similar career under other circumstances. This slave owner probably changed the view of many people about people from Africa. 

Unfortunately, the video says very little about the slave owner, who was also a secessionist.
