Louis Braille was never rich. He was always a poor blind man. People didn't use his braille until he died.
Louis Braille invented braille. It is used for blind persons to read.
The first blind person to use braille was probably one of Louis Braille's students at the Royal Institution for Blind Youth in Paris, where braille was developed. Unfortunately, the specific identity of the first blind person to use braille other than Louis Braille himself is not well-documented.
Louis Braille (as he was called) created a system where each letter of the alphabet was represented by a number of (maximum: 6) dots. For making those dots he originally used a stitching awl.
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.
In addition to developing the braille code, Louis Braille invented tools for writing it. The braille slate (a type of stencil for writing braille by hand) and stylus are still used by blind people for tasks like making grocery lists, writing down telephone numbers, and other little things for which a sighted person might use a pencil and paper.

Braille came into use by the blind people of the olden days.
Louis Braille chose to use six dots because it allows for a combination of different patterns and configurations that can represent letters, numbers, and symbols. This compact system makes it easier for blind individuals to read and write by touch. Each unique combination of raised dots corresponds to a specific character or symbol in the Braille system.
