Norman Siegel (born 1943) was the director of the New York Civil Liberties Union (NYCLU), New York's leading civil rights organization, under the umbrella of the nationwide American Civil Liberties Union (ACLU). Siegel served as director from 1985 until 2000.
Siegel attended Brooklyn College and NYU Law School with Rudy Giuliani, who later became mayor of New York City and NYCLU's frequent courtroom opponent.
Since ending his work at the NYCLU, Siegel entered private practice and has represented various activist groups including RodStarz and G1 of Rebel Diaz, Critical Mass, residents fighting the expansion of Columbia University and families against the Rudy Giuliani's 2008 campaign for President of the United States. He also frequently wrote op-ed columns at major New York City newspapers, such as the New York Times, Newsday, the New York Daily News, and the Amsterdam News. Siegel has taught a class at New Utrecht High School in Brooklyn, New York and has served on the boards of many foundations.
