Merton Miller received the Nobel Prize in Economic Sciences (jointly) in 1990 for pioneering work in the theory of financial economics.
His first academic appointment after graduation was at LSE as an assistant lecturer in American economic history in 1952 to 1953.
Miller's early work was focused on corporate finance, but after his appointment to the Chicago Board of Trade in the early 1980s his research concentrated on economics and regulation within the financial services industry, especially in the area of securities and options exchanges.
