The Washington Post and LA Times published an obituary last week on
Heinz Heinemann. He was a retired petroleum chemist. He was denied his
PhD in Germany because he was Jewish. He completed his degree in
Switzerland and immigrated to the US in 1938. In the early 1940s, he
developed ethanol for the Dominican Republic based on their sugar
supply. During WWII, "he was sent to Little Rock, AR to teach a group
of women how to work with petroleum catalysts. He solved the problem
of their unfamiliarity with basic math by teaching them how to use
slide rules".
