WASHINGTON — Abraham Nemeth, a blind mathematician and college professor who developed a widely used Braille system that made it easier for other blind people to become proficient in mathematics and science, died Oct. 2 at his home in Southfield, Mich. He was 94.
The cause was congestive heart failure, his niece, Dianne Bekritsky, said.
The Nemeth Braille Code for Mathematics and Science Notation was published in 1952. It has been revised from time to time, but it remains essentially unchanged and has become the standard way to teach blind students at every level of math, from 2+2=4 to advanced calculus and beyond. It is used throughout the United States, Canada, New Zealand and other countries.
Since the adoption of Nemeth’s Braille code, blind students have been able to enter the fields of science, engineering and technology in greater numbers. Full story for BostonGlobe.com subscribers.
