 Actually, Sethe was the first one to put forth a systematic theory of the Egyptian verb; it was no easy accomplishment, since the inflection of the Egyptian verb was done mainly by changing the vowels, and the Egyptians only wrote consonants.Among Sethe's students were Hans Jakob Polotsky and Alan Gardiner.Sethe's anthology, "Aegyptische Lesestuecke," is still doing sterling service to the beginners in the study of the language.
