Louis Nizer (6 February 1902 – 10 November 1994) was a noted Jewish-American trial lawyer. For a number of years, Nizer was listed in the Guinness Book of World Records as the "highest-paid lawyer in the world." He represented many celebrities in a variety of cases.
One of his most known cases involved representing Quentin Reynolds in his successful libel suit against the right-wing columnist Westbrook Pegler. Possibly for political reasons, this has been made into fictionalized mass media productions on stage and on television several times.
Another known case involved representing the broadcaster John Henry Faulk against AWARE, a right-wing organization, which has been described as being important in ending the "Hollywood blacklist", an entertainment industry blacklist against Communist sympathizers.
Less often mentioned in his role in anti-German propaganda and advocacy for a harsh treatment of Germany during and after WWII. He was involved in the anti-German Society for Prevention of World War III. In 1944, he published the anti-German book What To Do With Germany. See also Society for Prevention of World War III.
