Mark D. Wolfinger grew up in Brooklyn and holds a Bachelor of Science from Brooklyn College and a PhD in chemistry from Northwestern University. After seven years as a research chemist, in 1976, he packed his belongings, left his career behind and headed to Chicago to become a market maker on the trading floor of the Chicago Board Options Exchange (CBOE).
