Overview
John Calvin Coolidge Sr. (March 31, 1845 – March 18, 1926) was an American farmer, businessman and civic official from Plymouth Notch, Vermont. He is best known as the father of Calvin Coolidge, the 30th President of the United States, and for having administered the first presidential oath of office to his son at the family homestead following the death of President Warren G. Harding. Coolidge Sr. combined agricultural work with small-business activity and long-standing participation in local government.
Occupation and local roles
Coolidge Sr. operated a family farm and participated in village commerce. In the accustomed pattern of New England rural life of his era, he performed multiple civic duties and held elected or appointed municipal positions. His community responsibilities reflected the close interweaving of private enterprise and public service typical of late 19th- and early 20th-century Vermont towns.
- Farm proprietor and local businessman, managing homestead operations and village interests.
- Municipal officer who carried out functions such as notarial and justice duties, assisting with legal and civic matters in his town.
- Trusted community member whose standing in Plymouth Notch gave him an unusually visible role during a moment of national transition.
Presidential succession, August 1923
When President Warren G. Harding died in August 1923, Vice President Calvin Coolidge was visiting his family home in Vermont. In the early hours following the news, John Calvin Coolidge Sr. administered the presidential oath of office to his son at the family homestead, a brief, solemn ceremony that has become a distinctive anecdote of American presidential history. To remove any uncertainty about the formality of the succession, the new president later repeated the oath in Washington in a later, more formal setting.
Later life and legacy
Coolidge Sr. lived quietly after the national attention surrounding the 1923 inauguration. He died in 1926. The Coolidge family property at Plymouth Notch has since been preserved as a historic site, interpreted for visitors as part of the broader story of the Coolidge family and rural New England life. The homestead and associated buildings illustrate the domestic and civic environment that shaped both father and son.
