Re Pierce, you wrote:
(The only book he published during his lifetime was
_Photometric Researches_, which was an improvement on the methods for
determining the distance to stars: (a) classify them according to their light
spectra and (b) within each class, estimate their relative distances in terms
of their relative brightness.)
But his major employment was
at the US Coast and Geodetic Survey for 30 years. During that time, he taught
for 5 years as a part-time professor at Johns Hopkins U (from 1880 to 1885).
That was the time when he developed and published
the algebraic notation for first-order logic, and he gave full credit to some
of his students for critical ideas.
If he only published the one book, how do
people today know about his work in semiotics? There must be material
published somewhere, perhaps by biographers. Do you have any citations that
describe his material at a tutorial level?
