The history of the last name Thermidor

The surname Thermidor is a relatively modern name that originates from the French Revolutionary calendar. It was the name given to the 11th month of the year in the French Republican calendar, which was in use from late 1793 to 1805. The name Thermidor comes from the Greek words "thermos" meaning heat, and "dor" meaning gift, referring to the hot summer month.

The first recorded use of Thermidor as a surname dates back to the late 18th century during the French Revolution. It is believed that some individuals adopted the name as a way to show their support for the revolutionary ideals and the new calendar system.

One of the earliest known individuals with the surname Thermidor was François-Joseph Thermidor (1760-1828), a French lawyer and politician who served as a member of the National Convention during the Revolution. He was a supporter of the Jacobin faction and voted for the execution of King Louis XVI.

Another notable figure with the surname Thermidor was Marie-Jeanne Thermidor (1772-1850), a French writer and feminist activist. She was a vocal advocate for women's rights and published several works on the subject, including "Reflections on the Education of Women" in 1804.

In the 19th century, the surname Thermidor was also found in parts of Germany and Switzerland, likely due to the influence of the French Revolution and the adoption of French names in those regions.

One of the most famous individuals with the surname Thermidor was the German philosopher and writer, Friedrich Thermidor (1813-1890). He was a prominent figure in the German Romantic movement and wrote extensively on topics such as aesthetics, culture, and the human condition.

Another notable individual was the Swiss painter, Albert Thermidor (1865-1932), who was known for his landscapes and portraits depicting the rural life of Switzerland. His works are displayed in several museums across Europe.

While the surname Thermidor has its origins in the French Revolutionary calendar, it has since become a part of the cultural heritage of France and other European countries.
