John Calvin Coolidge, Jr. (July 4, 1872 – January 5, 1933), more commonly known as Calvin Coolidge, was the thirtieth 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 actions during the Boston Police Strike of 1919 thrust him into the national spotlight. Soon after, he was elected as the twenty-ninth Vice President in 1920 and succeeded to the Presidency upon the death of Warren G. Harding. Elected in his own right in 1924, he gained a reputation as a small-government conservative.
In many ways Coolidge's style of governance was a throwback to the passive presidency of the nineteenth century. He restored public confidence in the White House after the scandals of his predecessor's administration, and left office with considerable popularity. As his biographer later put it, "he embodied the spirit and hopes of the middle class, could interpret their longings and express their opinions. That he did represent the genius of the average is the most convincing proof of his strength."
