Eric R. Rosenfeld was a trader and principal at Long-Term Capital Management (LTCM), a major hedge fund that failed during the Russian financial crisis.
From 1979 to 1984, Rosenfeld was an assistant professor of finance at Harvard Business School. At HBS, he taught the first year finance course.
In July 1984, Rosenfeld joined Salomon Brothers and left in 1993. He then joined John Meriwether and a group of Salomon Brothers traders in starting Long-Term Capital Management.
About one year after LTCM's rescue, in 1999, he joined John Meriwether as a partner in JWM Partners LLC. He left JWM Partners to join Paloma Partners, a Greenwich fund-of-funds. In 2007, Rosenfeld founded Quantitative Alternatives LLC in Rye Brook, NY with Bruce Wilson and Robert Shustak. The firm closed in late 2007.Eric Rosenfeld in Wikipedia
