Louis Blanc (29 October 1811 – 6 December 1882) was a French politician and historian. He advocated for socialist reforms without revolution first, and called for the creation of job guarantees for the urban poor. Blanc coined the phrase "right to work", and his political and social ideas greatly contributed to the development of socialism in France. This photograph of Blanc was taken in 1848 by the French photographer Étienne Carjat.Photograph credit: Étienne Carjat; restored by JLPC
