It is one of the most commonly misspelled minerals in the lapidary market. It is often misspelled (and mispronounced) as fuschite, with a long 'u' and a long 'i'. In 1842 the material was named by Karl F. Emil von Schafhäutl in honor of Johann Nepomuk von Fuchs, a German chemist and mineralogist. His name is pronounced “fooks” - similar to the way you pronounce 'books' and 'looks'.
