The braille clock was invented in the late 19th century, with significant contributions made by Louis Braille, who developed the braille system in the 1820s. However, the specific design of clocks that incorporated braille for the visually impaired emerged later, with various models appearing in the early 20th century. These clocks allowed individuals to tell time by feeling the raised dots representing numbers.
