James Guillaume

James Guillaume (16 February 1844 – 20 November 1916) was a Swiss anarchist and writer who was a leading member of the Jura federation, one of the anarchist wings of the First International. Later, Guillaume would take an active role in the founding of the Anarchist St. Imier International.

Life Guillaume was born in London on 16 February 1844, the son of George Guillaume and his wife Marie Suzanne Glady. George Guillaume ran the London branch of a Neuchâtel watchmaking factory. His brother, also named George, would later become a communard.

In 1909, James Guillaume assisted Peter Kropotkin with the research in preparing his book, "The Great French Revolution, 1789-1793," particularly helping with regards to the resolutions (arrêtés) of 4 August 1789, where the Assembly declared that it is acting with both constituent and legislative power. Guillaume is said to have played a key role in Peter Kropotkin's conversion to anarchism.
