About our Speaker:
Jim Hopkins graduated from Eastern Illinois studying geology, physics, meteorology, and astronomy. He split his college experience with 3 years in the paratroops, serving in Alaska, and with both the 101st and 82nd Airborne Divisions. He began a 30-year teaching career at Naperville North High School and added 28 more years of teaching Astronomy and Meteorology at C.O.D. and Joliet Junior College in summers and in the evenings.
