Sherman Joseph Maisel (July 8, 1918 – September 29, 2010) was an American economist who served as a member of the Federal Reserve Board of Governors from 1965 to 1972. Research on mortgage policy conducted by Maisel led to the expansion of the roles played by Fannie Mae and Ginnie Mae in encouraging the broader availability of loans to homeowners. After his seven-year term expired in 1972, Maisel returned to California and resumed teaching at Haas until his retirement in 1986. He was a fellow of the American Finance Association, and was the organization's president in 1973.
