I doubt anyone teaching typing would know it unless you knew about the old typesetting terms, I used to be a graphic designer and everyone I asked when I was in school for it, didn't know what it was, they also couldn't tell me how big a cicero was, It took the internet for that Points (Fournier, 1737): In 1737 Pierre Fournier formulated the first definition of the point as being 1/12th of the French "Cicero" type size. The "Cicero" was then 0.1648 inches, so the Fournier point was approximately 0.013733 inches. This definition was originally presented in his booklet "Tables des Proportions qu'il faut observer entre les caractères." No wonder no one knew what it was...
