Lodovico Nabruzzi (25 June 1846 – 12 February 1916) was an Italian journalist and anarchist. He played a leading role in the dissensions between the revolutionary and evolutionary Italian socialists. He spent several years in exile in Switzerland and France, often forced to undertake menial work and often in trouble with the authorities. After returning to Italy his life continued to be difficult, and he suffered from mental health problems. Although he married and had four children the marriage did not last. He died alone in a public hospital.
