Braille code is a writing system which enables blind and partially sighted people to read and write through touch. Each cell represents a braille letter, numeral or punctuation mark.

Dr. Abraham Nemeth
Nemeth Code is the standard code of braille notation used for math and science. It was developed by Dr. Abraham Nemeth in 1946, and was adopted by BANA (Braille Authority of North America) in 1952 as the standard code to represent mathematic and scientific notation, using the 6-dot braille cell.

Abraham Nemeth
Abraham Nemeth, whose frustrations in pursuing an academic career in math prompted him to develop the Nemeth Code, a form of Braille that greatly improved the ability of visually impaired people to study complex mathematics, died on Wednesday at his home in Southfield, Mich. He was 94.

1946
Nemeth Code is a special type of braille used for math and science notations. It was developed in 1946 by Dr. Abraham Nemeth as part of his doctoral studies in mathematics.

Nemeth Braille Code
Ultimately, he developed the Nemeth Braille Code for Mathematics and Science Notation, which was published in 1952. The Nemeth Code has gone through 4 revisions since its initial development, and continues to be widely used today.

The Nemeth Braille Code for Mathematics is a Braille code for encoding mathematical and scientific notation linearly using standard six-dot Braille cells for tactile reading by the visually impaired. The code was developed by Abraham Nemeth. Nemeth Braille is just one code used to write mathematics in braille.

The name Nemeth comes from the Russian word “Nemchin,” which means German; the same word in Old Slavic was used to denote any foreigner. Nemchinov, or any variants of this name ending in “ov/ev” were patronymic surnames created by adding the suffix to the personal name.

Mathspeak is a free foreign language learning resource for secondary schools that is available in six European languages. The ten courses enable students to perform mathematics in a foreign language at the same level they do in their native language.

All braille is written as a combination of six dots per cell. The dots are arranged as two vertical rows of three dots (or, depending on your perspective, three horizontal rows of two dots.) A single letter can be represented by as few as one, or as many as five dots.

Reading Braille People read Braille by moving their fingertips from left to right across the lines of dots. Developed in the early 1800s by Louis Braille, Braille is a series of characters, or “cells,” that are made up of six raised dot patterns, arranged in a rectangle containing two columns of three dots each.

Nemeth Name Meaning Hungarian (Németh): ethnic name from Hungarian német ‘German’. Compare Nemec. The name is also found in Germany and Austria.

For the surname, see Németh. The Nemeth Braille Code for Mathematics is a Braille code for encoding mathematical and scientific notation linearly using standard six-dot Braille cells for tactile reading by the visually impaired. The code was developed by Abraham Nemeth. The Nemeth Code was first written up in 1952.

The Nemeth Code Book (1972) opens with the following words: This Braille Code for Mathematics and Science Notation has been prepared to provide a system of symbols which will allow technical literature to be presented and read in braille.

BANA Position Statement— This method of switching between the Nemeth Code and Unified English Braille has been developed to ensure the continued viability of the use of the Nemeth Code for mathematics.

An unambiguous switching method eliminates code conflicts and makes it possible for accurate translation in either direction to occur, so that mathematics can be communicated between print users and braille users using Nemeth Code.
