 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 United States Supreme Court justices in history, particularly for his "clear and present danger" opinion for a unanimous Court in the 1919 case of "Schenck v. United States", and is one of the most influential American common law judges, honored during his lifetime in Great Britain as well as the United States.
 Holmes retired from the Court at the age of 90 years, making him the oldest Justice in the Supreme Court's history.

Linder v. United States, 268 U.S. 5 (1925) , is a Supreme Court case involving the applicability of the Harrison Act.
 The Harrison Act was originally a taxing measure on drugs such as morphine and cocaine, but it later effectively became a prohibition on such drugs.
 However, the Act had a provision exempting doctors prescribing the drugs.
 Dr. Nick Linder prescribed the drugs to addicts in Moore, Oklahoma, which the federal government said was not a legitimate medical practice.
 He was prosecuted and convicted.
 Linder appealed, and the Supreme Court unanimously overturned his conviction, holding that the federal government overstepped its power to regulate medicine.
 The opinion of the court was written by Justice James Clark McReynolds and states, "Obviously, direct control of medical practice in the states is beyond the power of the federal government."

 A Republican lawyer from Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of that state.
 His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action.
 Soon after, he was elected as the 29th vice president in 1920 and succeeded to the presidency upon the sudden death of Warren G. Harding in 1923.
 Elected in his own right in 1924, he gained a reputation as a small-government conservative, and also as a man who said very little, although having a rather dry sense of humor.
