For almost four decades, Mrs. Mergenthaler-Walter shaped Schule Schloss Salem with passion and dedication. For more than a decade, she served as head teacher and executive director. She came to Salem in October 1985 as a teacher of biology and chemistry and quickly established herself as a remarkable educator who stood out for her collegiality and extensive preparation.
Her role was not limited to teaching, however. She was also part of the Ecology Core Group, involved in drafting proposals to the German Environmental Foundation, and managed to pick up on important issues immediately and implement them consistently. In 2000, she was appointed assessor of the teaching profession and a year later, she became Studienrätin.
