 He worked there until being deported in January 1957.In France while completing his residency, Fanon wrote and published his first book, "Black Skin, White Masks" (1952), an analysis of the negative psychological effects of colonial subjugation upon black people.Originally, the manuscript was the doctoral dissertation, submitted at Lyon, entitled "Essay on the Disalienation of the Black", which was a response to the racism that Fanon experienced while studying psychiatry and medicine at university in Lyon; the rejection of the dissertation prompted Fanon to publish it as a book.
