Oliver Wendell Holmes Jr.
D.O.B. March 8, 1841; Died: March 6, 1935
Significance: He coined the phrase "clear and present danger." Together with Justice Louis Brandeis, Justice Holmes was a famous dissenter during the Red Scare era of the early 20's. Their dissenting opinions have come to be viewed as fundamental in defining free speech and eventually press freedoms as constitutional rights.
Notable for: Schenck v. United States (1919); Abrams v. United States (1919); Gitlow v. New York (1925).
