Intro to Financial Markets, taught by Burton Malkiel. As an impressionable 20 year old with no background in finance, it introduced me to passive investing, Vanguard, the efficient market theory and the power of compound interest. It's funny, 20+ years later I still think back to some specific lectures in his class whenever I encounter the CAPM or Black-Scholes in my day job. Prof. Malkiel helped me develop a healthy skepticism about claims in finance that has served me really well in my career and my personal finances.
