So sorry for your loss. Earl was my undergraduate advisor while I was at Iowa State in the early 1970s. He also taught me food chemistry at the undergraduate and graduate level and I worked in his lab growing and grinding soy beans for his long-running linolenic acid project and running the ingenious "smell testing" apparatus he constructed for analyzing hog house odors. He also was the Department Head when I returned for graduate studies in the late 1980s. I will always remember him fondly for his kind manner and slow witty Texas humor. I just retired as a professor at Penn State University and I know now how great a professor and person he really was. He will be missed.
