Oliver Wendell Holmes Jr. is among the most famous of the U.S. Supreme Court justices. Born to a prominent Boston family, Holmes was wounded at the Civil War battles of Ball’s Bluff, Antietam and Chancellorsville. After graduating from Harvard Law School in 1866, he prepared a series of lectures that were published as “The Common Law” in 1881. Holmes then served on the Supreme Judicial Court of Massachusetts from 1882 until his appointment to the U.S. Supreme Court in 1902. During his 30 years with the country’s highest court, he became known for his “clear and present danger” argument for the limitation of free speech and his convincing dissents.
