<human>:  Why is it called Braille?
<bot>: It’s named after its inventor, Louis Braille, who was blind from a very young age. He invented a system of dots and dashes that could be used to read and write with a device called a braille embosser. Braille is used today to read and write with the braille embosser, but there are many other ways to read and write with braille.
