I was a high school mathematics teacher...the one recognized example of the startification barriers between high school teachers and university professors.
In the early 1900s, I gave mathematical presentations at annual conferences sponsored by NCTM, MAA, and AMS....and even at the International Mathematical Congress at Toronto in 1924.
My specialty was constructing physical models of polyhedra, and even discovered some new stellations of icosahedra.
Even though I produced mathematical results and my models were shown in cabinets at MIT and Brown University, university professors treated me with "condescension."
The one mathematician who agreed to interact with me was the famous geometer H.S.M. Coxeter, as together we prepared the book The Fifty-Nine Icosahedra.
Unfortunately, the book was never published, because I feared the algebraic symbols used by Coxeter; I could not understand his use of concepts from group theory.
Today, I am remembered as the person who tried to cross the division between two-cultures, and failed....though journalists and students in math clubs all felt I had succeeded.
