On Abraham Nemeth, the developer of Braille
for blind students of mathematics —
"… he began tinkering with the six-dot cell
that is the foundation of Braille."
For a different six-dot cell, see Nocciolo .
"Throughout his life, he dedicated much of his
spare time to creating Braille versions of Jewish
texts, including helping to proofread a Braille
Hebrew Bible in the 1950s." — Nemeth's obituary
