American jurist Oliver Wendell Holmes, Junior, son of Oliver Wendell Holmes Sr., served as an associate justice on the Supreme Court of the United States from 1902 to 1932; many of his opinions greatly influenced the American concept of law. Noted for his long service, his concise and pithy opinions, and his deference to the decisions of elected legislatures, he is one of the most widely cited Supreme Court justices in history, particularly for his "clear and present danger" majority opinion in the case of Schenck v. United States (1919), as well as one of the most influential American common-law judges.
