On October 19 Instructor John Koellner passed away after 43 years at IU South Bend. Koellner was a valued member of our department and often taught multiple sections of the fall and spring semesters of the freshman chemistry laboratory classes C125 and C126. His passing was quite sudden after resigning from teaching at the start of this semester. Please visit the South Bend Tribune for Koellner's obituary and this blog for a recent profile. We miss you Koellner!
