Joseph Auguste Anténor Firmin (18 October 1850 – 19 September 1911), better known as Anténor Firmin, was a Haitian barrister and philosopher, pioneering anthropologist, journalist, and politician. Firmin is best known for his book De l'égalité des races humaines (English: "On the Equality of Human Races"), which was published in 1885 as a rebuttal to French writer Count Arthur de Gobineau's work Essai sur l'inégalité des races humaines (English: "Essay on the Inequality of Human Races"). Gobineau's book asserted the superiority of the Aryan race and the inferiority of Blacks and other people of color. Firmin's book argued the opposite, that "all men are endowed with the same qualities and the same faults, without distinction of color or anatomical form. The races are equal". He was marginalized at the time for his beliefs that all human races were equal. Source: Wikipedia (en)
