“I most fondly remember working with him in his lab on my junior high school science fair project. He taught me about thin layer chromatography using slides he had in his lab. We found candies and other foods that used the cancer-causing red dye number 5 that we were all so worried about during the 1970s. He helped me win first prize!”—Michelle Van De Graaff, daughter
