Nemeth Code

Nemeth Code is an extension to Braille to handle mathematical notation, named after its creator Abraham Nemeth. It replaced earlier systems such as the Taylor Code which Nemeth found to be inadequate. Its earliest version was published in 1952, with later revisions over the years until it was made part of Unified English Braille in 1992.
