This source is notable for claiming Saunderson's teaching load was 7 to 8 hours/day, as well as naming his children but not the woman who bore them. The early smallpox claimed his eyes, not just his sight. I wonder if there's an unnamed prosthetist who labored with whale ivory, or perhaps the empty sockets contributed to his early death?
And for great detail on tactual math tools: http://s22318.tsbvi.edu/mathproject/ch6-sec1.asp a portion of "Project Math," a thorough research endeavor aimed at schooling teachers to produce math-literate blind students. Of particular utility is the Handbook for Spoken Mathematics, updated from Larry Chang's crucial work. Its information is accessible to fully, partially and not-at-all sighted folks on equal footing.
OK, done now.
Did you learn to use an abacus, or were talking calculators readily available, or did you successfully avoid math in total?
