John Calvin Coolidge, Jr. (July 4, 1872 – January 5, 1933) was the 30th President of the United States (1923–1929). A Republican lawyer from Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of that state. His conduct during 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. This book covers his life and history and his influences on the United States.
