Here's the obituary. Frankly, I've always doubted the bit about Harvard. The information must have been given by his (second) wife or one of his children. Maybe they, um, tarted up his resumé a tad.
Here's what Seaborg said:
"Two people inspired me. One was Dwight Logan Reid, my chemistry and physics teacher at David Starr Jordan High School, Los Angeles. Up until the time I entered high school, I had no exposure to science and, therefore, little knowledge of its possibilities. I chose literature as my major subject, and I took no science until my junior year when, in order to meet the college requirement, I took a chemistry course. Largely due to the enthusiasm and obvious love of the subject displayed by my teacher, Dwight Logan Reid of Jordan High School in Los Angeles, chemistry captured my imagination almost immediately. I had the feeling, 'Why hasn't someone told me about this before?' Dwight Logan Reid didn't just teach chemistry. He preached chemistry."
Seaborg also said: "I could have told you again that I fell in love in the ninth grade with another girl, Vivian Dawson, and again sort of in college. That was the daughter of Dwight Logan Reid. She wound up going to UCLA, Beth Reid, and I dated her for about a year."
