own private Braille code. So he asked me to
teach him my code. When I showed him the
code, he really liked it. Dr. Witcher happened to
be a member of the Mathematics Subcommittee
of the Joint Uniform Type Committee. This committee, an ancestor of BANA, was responsible for
Braille codes in the U.S. and England (the word
"Joint" referred to the U.S.A. and England).
[Editor's Note: A table of integrals is a long list of
formulas for performing a calculus operation
called integration. A table of integrals is part of the
holy liturgy for calculus students, engineers,
physicists, and many others.]
Q. This really brings back memories for me.
When I was a freshman in college, my new friend,
David Holladay, asked me if I had a table of integrals in Braille. I told him that my Braille calculus
textbook had a table of integrals at the end. He
said that he had a much better one in print and
wanted to Braille it for me over Christmas vacation. He asked me how the Braille math code
worked and spent half an hour taking one page of
notes on Nemeth Code. He took my Perkins
Braille writer home over the vacation and did a
really good job of Brailling his favorite table of integrals. 
Anyway, what happened after Dr.
Witcher became a fan of your private Braille math
code?
