The former National Machinery Corporation Lecture Hall (Glennan 421) has been renovated to a state-of-the-art classroom and rededicated as The Wayne Zahn Lecture Hall, through the generous gift from Wayne and Ginny Zahn. Wayne Zahn graduated from Case Institute of Technology with a Bachelor of science in Mechanical Engineering class of 1941 and went on to become the president of National Machinery Corporation in Tiffan, Ohio.
