There are several stories about the origin of these pancakes.

Austrian Emperor Francis Joseph I (1830-1916) got lost on an hunting expedition. Tired and hungry, he was offered these pancakes by a farmer's wife. When he praised, the lady said that it was just "schmarrn". Emperor in return said that it is  Kaiser's schmarrn (Emperor's mess).
Austrian Emperor's wife Elisabeth of Bavaria (Sisi) was obsessed with maintaining her figure. So she ordered for low fat desserts. One day Royal chef prepared these rich pancakes & the Queen refused to eat them. But the Emperor enjoyed his portion & ate hers too. Thus "Kaiser-Schmarrn" became the popular dessert of Austria.
