He was a professor of physics and applied mathematics at the Faculty of Philosophy of University of Olomouc, where he greatly influenced his student Gregor Johann Mendel, later known as "The Father of Genetics".
Friedrich Franz graduated in 1831 the University of Prague as Doctor of Philosophy and Liberal Arts.
Before he came in 1842 to Olomouc, he taught physics at a philosophical institute (type of grammar school) in Brno (Brünn).
He started experimenting already in 1839, the same year that Louis Daguerre developed this method of taking photographs.
After the Austrian government dissolved the Olomouc Faculty of Philosophy following the students' and professors' participation on 1848 revolution, Franz became briefly the rector of the University in 1852, before he left and became a director of a grammar school in Salzburg, while later he was a Premonstratensian prelate in Nová Říše (Neureisch).
