Dr. Nemeth was blind since birth, but he invented many technological devices to make his life easier. I recall a Friday night get together at Rabbi Efry Spectre’s home during high school when Dr. Nemeth was the guest speaker. He showed the 20 or so teens in the room how he developed a wrist watch that would tell him the time just by touching it. He also showed us the Braille siddur (prayerbook) that he uses.
Dr. Nemeth taught math for 3 decades at the University of Detroit and then started their Computer Science department. In terms of his lasting legacy, his entry in Wikipedia explains that Dr. Nemeth developed “the Braille code that would more effectively handle the kinds of math and science material he was tackling. Ultimately, he developed the Nemeth Braille Code for Mathematics and Science Notation in 1952. The Nemeth Code has gone through 4 revisions since its initial development, and continues to be widely used today. Nemeth is also responsible for the rules of MathSpeak, a system for orally communicating mathematical text. In the course of his studies, Nemeth found that he needed to make use of sighted readers to read otherwise inaccessible math texts and other materials. Likewise, he needed a method for dictating his math work and other materials for transcription into print. The conventions Nemeth developed for efficiently reading mathematical text out loud have evolved into MathSpeak.
Nemeth was instrumental in the development of Unified English Braille (UEB) from 1991 to at least 2001, though he eventually parted ways with others developing that code, and instead worked on a parallel effort called the Universal Braille System (sometimes abbreviated as NUBS with his name appended to the front). As of 2012, UEB was officially adopted by BANA as the standard for literary braille, but Nemeth Code was also fully retained as an optional official coding system. Work on NUBS may continue, or it might be merged into a future rules-update to the official Nemeth Code (the most recent official rules-update to Nemeth Code was in 2013).”
I’ll miss seeing him in his regular seat at Adat Shalom and watching as a committed core of volunteers would escort him in and out of the sanctuary. Baruch Dayan Ha-Emet – may his memory be for enduring blessings and may the blind continue to benefit from his contributions.
