Louis Braille was never rich. He was always a poor blind man. People didn't use his braille until he died.
Louis Braille developed a system of raised dots that can be felt with the fingers to represent letters and symbols. Through touch, blind people can read and write using Braille by tracing their fingers over the dots on a page. He taught blind people to use Braille through his school in Paris, where he demonstrated the method and helped students learn how to read and write with it.
