Augustine “Augie” Miceli Sr., the longest-tenured faculty member at Calvert Hall College High School, who taught thousands of students in a 60-year career as math teacher and football coach, died Saturday of acute myeloid leukemia at the Gilchrist Center hospice in Towson. He was 86 years old.

Mr. Miceli, the gregarious son of Italian immigrants, channeled the academic struggles he experienced in high school into his approach to teaching, arriving before school and staying afterward to provide extra guidance to students who needed it, said his son, Augie Miceli Jr., 55, of Towson.
