Early life
Lewis was born in Dayton, Ohio, USA, in 1947 and graduated from the Groton School and Harvard University (AB 1969).

Cambridge Associates
After working at the Boston Company, then one of the largest investment managers, Lewis in 1975 co-founded and served as co-chief executive and then chief executive of Cambridge Associates LLC, an investment advisor to American research universities and colleges representing over three-quarters of U.S. higher education endowment assets, other non-profits, international organizations, and families. Lewis was a co-inventor of what became known as the American University style of institutional investing, which gave American university endowment funds the highest investment returns in the world among institutional investors, and which became widely emulated. Cambridge Associates also became known for its claim to avoid the conflicts of interest so endemic to Wall St., conflicts that became especially apparent during the Crash of 2008. Cambridge Associates has claimed that its mode of “conflict free” services represents an important innovation in American finance.
