Early in the 70's, Carl developed and taught an English composition course, "Inter-language Concepts," for educationally disadvantaged students which focused on teaching language concepts common to both English and German. Through this course he brought minority students into the German Department, and every summer for four years Carl took four students to Austria where they were enrolled in an intensive German language course and lived with Austrian families.

In 1990, Carl was appointed Director of the Collins Living-Learning Center by the College of Arts and Science. Carl's inspired at Collins were well received by the University and resulted in his receiving one of two University Distinguished Service Awards and a Bicentennial Medal of Honor.  Over the years he served in Bloomington on the boards of Middle Way House, Monroe County Ministry and United Way and the Ziegler Family Foundation.  (Excerpted with thanks to Allen Funeral Home, Bloomington IN)
