Curious About A History Teacher, From Sylvania High, 1966-7 Class Year

I wonder if any of you members remember, or know, whatever happened to a World History teacher who taught only one year(I believe)at Sylvania High School during the 1966-7 class year? Her name is Elin Richardson.I remember she was a Teachers' Union official after she left Sylvania, but have no idea if she still is, or even if she returned to teaching. Sylvania at the time was a strongly conservative city and so was the School system. She was as I recall, an activist, and the sort of person who was not afraid to challenge "the system". Her class was basically the only one I had, that I ever "got anything" out of, the three years I attended SHS. Anyhow, thanks to all for reading this!
