Ron Kahn is currently travelling. Let's copy the citation here

Before Markowitz, mathematical analysis of investing was limited to Graham & Dodd-type analysis of individual stocks and John Burr Williams’ Theory of Investment Value, also focused on individual investments. Markowitz provided a precise mathematical definition of risk as standard deviation of return, and focused on return and risk at the portfolio level, leading to modern portfolio theory and much of the portfolio analytics we run today. Like many profound breakthroughs, it looks obvious in retrospect. -- [Ronald Kahn in 2023]
